Quick answer: The biggest pricing mistake in ecommerce is setting prices once and leaving them. High-growth brands use anchoring to make any price look reasonable, bundle pricing to increase AOV by 25-40%, charm pricing to lift conversion by 3-5%, and competitive monitoring to stay in range without racing to the bottom.
Introduction
A 1% improvement in price realisation delivers a 10% increase in operating profit. McKinsey’s research on this finding, published two decades ago, still holds up — and most ecommerce brands ignore it completely.
They set prices at launch, maybe adjust for a sale, and otherwise leave pricing on autopilot. Meanwhile, their competitors are running controlled tests, monitoring price elasticity, and using anchoring techniques that make customers feel like they are getting value at every price point.
Pricing is not just a number on a product page. It is a psychological cue that tells shoppers how to feel about your brand, your quality, and the deal they are getting. Get it right and you increase conversion rate and average order value simultaneously. Get it wrong and you leave money on the table even when traffic is strong.

1. Price Anchoring: The Psychology That Changes Everything
Price anchoring is the practice of presenting a higher reference price alongside your actual price to make the actual price feel like a bargain. Your brain is not good at evaluating absolute prices — it evaluates prices relative to other numbers it has been shown.
The classic anchor:
– Crossed-out “RRP: $149” next to your selling price of $89
– “Was $120, Now $79”
– A premium version at $199 that makes your $89 standard version feel affordable
The research behind it: Kahneman and Tversky’s anchoring effect studies showed that exposure to any number — even an irrelevant one — influences subsequent numerical judgements. For pricing, this means that showing a $200 price before revealing a $80 price makes $80 feel dramatically different than presenting $80 on its own.
Three types of price anchors in ecommerce:
1. Strike-through pricing. The most common anchor. Show the original/RRP/competitor price with a strikethrough, then your price below. Important: the original price must be genuine. Many jurisdictions (Australia, UK, EU) have pricing regulations that prohibit fake “was” prices. In Australia under the Competition and Consumer Act, a struck-through price must reflect a price you actually sold the product at for a reasonable period.
2. Tiered/Good-Better-Best pricing. Present three versions: Basic ($29), Standard ($59), Premium ($99). Most buyers will choose the middle option. But the $99 Premium anchors the Standard at $59, making it feel accessible. Williams-Sonoma famously added a $400 bread maker to their range after a $275 bread maker wasn’t selling — once the $400 version appeared, $275 felt reasonable and sales of it increased significantly.
3. Bundle anchoring. Show the sum of individual prices (“Individually: $158”) alongside the bundle price (“Bundle: $109”). The math shows 31% savings; the anchor makes the bundle the obvious choice.
When to use anchors strategically:
– Product pages: always have a reference price visible
– Cart page: show the total “before discount” vs “your price”
– Email campaigns: show what non-subscribers pay vs subscriber price
– Checkout: display items with their individual prices before the bundled discount
Key takeaway: You are always in control of the reference price customers compare against. Surfacing the right anchor at the right moment is a free conversion optimisation.
2. Bundle Pricing: The AOV Multiplier
Bundle pricing groups multiple products at a combined price lower than buying them individually. Done well, it increases average order value by 25-40% and moves slower inventory by coupling it with popular products.
The bundle maths:
If your AOV is $65 and you introduce a bundle that converts 30% of buyers at $95 (vs 70% buying single products at $65), your blended AOV is:
– (0.30 × $95) + (0.70 × $65) = $28.50 + $45.50 = $74 blended AOV — a 13.8% increase from a single bundle offer.
Now add two bundle options, push that 30% to 45%, and the AOV impact compounds.
Four bundle types for ecommerce:
Pure bundles: Only available as a bundle — individual items cannot be purchased separately. Works for consumables and complementary products (skincare routine kit, coffee starter pack).
Mixed bundles: Items are available individually but discounted when purchased together. The most common ecommerce bundle type.
Cross-sell bundles: “Frequently bought together” — surface products commonly purchased in the same session. Amazon’s algorithm-driven FBT section drives a reported 35% of their revenue.
Tiered bundles: Buy 1 for $15, 2 for $25, 3 for $32. Incentivises multi-unit purchase without requiring a formal bundle product listing.
Bundle construction principles:
- Pair a high-margin product with a lower-margin or slow-moving product. This moves inventory without discounting the slow mover on its own (which tanks perceived value).
- The discount should feel meaningful but not suspicious. 10-20% is the sweet spot. 40%+ makes buyers question the original pricing.
- Name your bundles meaningfully: “Morning Routine Kit” outperforms “3-Product Bundle” in testing by 20-30% conversion rate.
- Show the individual item prices. The contrast makes the bundle value tangible.
Shopify bundle implementation:
– Use Shopify’s native bundling (available on plans with Shopify Bundles app)
– For more flexibility, apps like Bold Bundles, Bundler, or PickyStory
– Ensure inventory tracking works correctly — bundle inventory should decrement each component’s stock
Key takeaway: Every store should have at least one bundle live. Start with your two best-selling complementary products and test a 15% bundle discount.
3. Charm Pricing and Price Format Psychology
Charm pricing is the practice of ending prices in .99 or .95. The effect is well-documented: $19.99 consistently outperforms $20 even though the difference is one cent. The brain reads from left to right and encodes the first digit — so $19.99 registers as “nineteen-something” before the cents are processed.
A MIT and University of Chicago study tested this with women’s clothing. The $39 version outsold the same item at $34 and $44. The “just below round number” price outperformed even a genuinely lower price.
When to use charm pricing:
– Fashion, beauty, electronics, mass-market goods: yes, always
– Luxury goods: no — $199.99 undermines the premium signal that $200 (or $197) sends
– Subscription prices: $29.99/month vs $30/month — charm pricing wins
Price format psychology beyond .99:
Left digit effect: Dropping from $30 to $29 (crossing the “tens” boundary) is perceived as a larger reduction than dropping from $30 to $28 (same $2 reduction but no “tens” boundary crossed).
Font size and positioning: Smaller font sizes for prices in premium contexts subtly signal lower cost to the brain. Showing the sale price in a smaller font than the crossed-out original is counterintuitive but tested to work in some categories.
Currency symbol placement: Studies show that removing the currency symbol (showing “85” rather than “$85”) reduces the psychological “pain of paying.” Some high-end restaurant menus use this tactic. For ecommerce, this is less practical but worth noting.
Free shipping threshold: “Free shipping on orders over $75” is itself a pricing lever — it lifts AOV by incentivising buyers to add one more item. Set the threshold at 20-25% above your current AOV.
Price localisation for international markets:
– AUD, USD, GBP, AED, JPY, CAD, QAR all have different psychological thresholds
– A price that feels mid-range in AUD may feel expensive in INR or cheap in GBP
– Always price in local currency — 73% of international shoppers abandon when prices are shown in USD on a non-US site (PayPal research, 2024)
Key takeaway: Charm pricing is not a trick — it is how buyers process numbers. Use .99 endings for volume products, avoid them for luxury positioning.
4. Competitive Price Monitoring
You do not need to be the cheapest competitor. You need to know where you sit relative to the market and be intentional about it.
Manual monitoring (free, for smaller catalogs):
For a catalog under 200 SKUs, a spreadsheet-based monitoring system works well. Set a Google Sheets with product names, your price, and competitor prices. Use ImportXML or a Google Sheets add-on (like ImportFromWeb) to pull competitor prices automatically on a schedule.
Example formula for pulling a price from a competitor’s product page:
=ImportXML("https://competitorsite.com/product", "//span[@class='price']")
This breaks when competitors change their HTML, but it is a free starting point.
Automated monitoring tools:
Prisync: Tracks competitor prices across unlimited SKUs and sends alerts when prices change. $59-$229/month. Best for mid-sized catalogs (100-10,000 SKUs).
Wiser (now part of CommerceIQ): AI-driven competitive intelligence with MAP compliance monitoring. Enterprise pricing.
Price2Spy: Multi-channel price monitoring including marketplaces (Amazon, eBay). From $19.95/month.
Ahrefs (for competitor content and positioning, not prices): Understanding what your competitors are ranking for and how they position their products is as important as knowing their prices.
Positioning strategy options:
Price matching: Risky. Once you compete purely on price, you are in a race to the bottom. Only viable if you have structural cost advantages (volume purchasing, own-manufacturing, dropshipping direct from supplier).
Value pricing: Set prices 5-15% above competitors and invest the margin difference into better packaging, customer service, or content that justifies the premium. This is how DTC brands consistently win against Amazon on their own SKUs.
Premium positioning: 20-50%+ above market. Requires strong brand differentiation, superior product photography, social proof, and a clear reason for the price gap. Luxury brands, hand-made goods, and specialist equipment can sustain this.
Dynamic matching: Adjust prices based on competitor moves, demand signals, and inventory levels. See section 5.
Key takeaway: Know your position in the market. Unintentional pricing (you set a price once and never checked competitors) is the most common margin leak in mid-market ecommerce.
5. Dynamic Pricing Considerations for Ecommerce
Dynamic pricing — changing prices based on demand, time, inventory, and competitor data — is standard practice in travel, rideshare, and Amazon’s marketplace (where prices can change hourly). For smaller ecommerce brands, it is less common but increasingly accessible.
When dynamic pricing makes sense for ecommerce:
High-demand/low-inventory situations: As stock drops below a threshold (e.g., fewer than 20 units), automatically increase price or remove discounts. This maximises revenue on scarce inventory.
Seasonal demand curves: Products that are highly seasonal (Christmas decorations, summer swimwear) can be priced higher at peak demand and discounted to clear at end-of-season — but in an automated, data-driven way rather than ad-hoc.
Personalisaton: Showing different prices or offers based on buyer history, geography, or acquisition source. Note: some jurisdictions (notably EU/UK) are tightening regulations around price discrimination.
When dynamic pricing is risky:
Customer trust damage: Customers who see the price change between sessions feel manipulated. If your brand is built on transparency, dynamic pricing can undermine it.
Perceived price gouging: Raising prices during a shortage or emergency event is illegal in many jurisdictions and will generate social media backlash regardless.
Brand positioning conflict: If you position as a premium, stable brand, erratic price movements send the wrong signal.
Practical dynamic pricing for Shopify:
Apps like Bold Discounts, Pricefy, or Prisync can automate rule-based price changes. Rules like “if stock < 20, remove all discounts” or “if competitor price drops 10%, match within $2” can be set without custom development.
For simple demand-based pricing, Shopify’s native scripts (on Plus) or custom metafields with price rules can be used.
Key takeaway: Dynamic pricing is powerful but demands careful brand and regulatory consideration. Start with inventory-based rules (remove discounts when stock is low) before adding complexity.
6. Price Testing: How to Run a Proper Price Experiment
Testing prices on a live store is difficult because you cannot show different prices to different users simultaneously without risking customer backlash if discovered. But you can test across time or across product variants.
Time-based testing: Run price A for 4 weeks, then price B for 4 weeks, and compare conversion rate and revenue per session. Control for seasonality by comparing to the same period in prior years.
Variant-based testing: Create two product listings (identically positioned) with different prices and measure relative performance. Works for products where buyers are unlikely to see both listings simultaneously.
New product launch testing: A new product has no price history for customers to compare against. Launch at a higher price and test downward. It is easier to discount later than to raise a price customers have anchored to.
What to measure:
– Conversion rate (not just revenue — a higher price may reduce conversion but increase total revenue)
– Revenue per visitor
– Return rate (higher prices with false value claims lead to more returns)
– Customer lifetime value (price-sensitive customers often have lower LTV)
7. Pricing by Category: What Works Where
Fashion: Charm pricing (.99) works. Tiered Good-Better-Best works. Avoid frequent deep discounts — they condition buyers to wait for sales. Zara never discounts until end-of-season; H&M discounts constantly. Zara’s margins are significantly higher.
Beauty/skincare: Price anchoring to clinical or professional pricing works (“RRP at salons: $120, our price: $68”). Subscription/bundle discounts drive LTV. Premium packaging justifies premium prices even for similar formulations.
Electronics/tech accessories: Competitive pricing is essential — these categories are comparison-shopped aggressively. Differentiate on warranty, service, and brand trust rather than price alone.
Health supplements: Subscription model with monthly savings (15-20%) drives predictable revenue and LTV. Price per serving or per day is more persuasive than total price.
Home goods: Bundle pricing (matching sets, “complete the look”) outperforms individual product pricing. Mid-high price with premium photography converts better than low price with poor presentation.
8. Common Pricing Mistakes That Kill Margin
Racing to the bottom. Matching or undercutting competitor prices without understanding your own cost structure leads to selling below margin. Know your landed cost, fulfilment cost, and customer acquisition cost before setting a price.
Discounting your best-sellers. Discounting high-demand products you could sell at full price is pure margin destruction. Save discounts for slow-moving inventory and new customer acquisition.
Inconsistent prices across channels. Different prices on your website, Amazon, and eBay trains customers to shop around for the lowest price rather than buying from you directly.
Ignoring price elasticity. Some products can bear a 20% price increase with minimal volume impact. Others will see a significant conversion drop. You will never know without testing. Most brands assume more elasticity than actually exists.
Not localising prices for international markets. Showing AUD prices to US customers or GBP prices to Australian customers creates friction and signals you are not really set up for that market.
Key takeaway: Pricing mistakes are usually errors of omission — not testing, not monitoring, not segmenting. The margin you protect through better pricing hygiene goes straight to your bottom line.

FAQ
Q: Is it legal to use a “was” price that was only briefly valid?
This varies by jurisdiction. In Australia, the ACCC’s guidelines state a struck-through price should reflect a price you actually sold at for a “reasonable” period. Fleetingly high prices set just to create a dramatic discount are considered misleading under the Competition and Consumer Act. UK and EU have similar rules. Always use genuine reference prices.
Q: How much should a bundle discount be to drive uptake without destroying margin?
10-20% is the sweet spot for most categories. Below 10% is not compelling enough to change behaviour. Above 25% starts to erode margin significantly and can make individual product prices look overpriced. Test with 15% first.
Q: Does charm pricing work for high-ticket items?
Not typically. For products above $200-300, round numbers signal confidence and quality. $497 or $499 instead of $500 can work for digital products (where the pricing convention is strong), but for physical premium products, $200 is usually better than $199.99.
Q: How do I monitor competitor prices without expensive tools?
For catalogs under 100 SKUs, Google Sheets with ImportXML can pull competitor prices automatically. For larger catalogs, Prisync starts at $59/month and pays for itself quickly. You can also set up Google Alerts for competitor product names and “price” to catch promotions.
Q: Should I have a MAP (Minimum Advertised Price) policy if I sell through resellers?
Yes, if brand consistency and margin health matter. MAP policies protect your brand’s perceived value and prevent resellers from undercutting you. They require a formal agreement with each reseller. Tools like Price2Spy can monitor MAP compliance across resellers automatically.
Q: What is price elasticity and how do I measure it?
Price elasticity measures how much demand changes when you change your price. A product with high elasticity sees big volume drops when you raise price; low elasticity means volume stays stable. Measure it with timed price tests on Shopify — raise price by 10%, hold for 4 weeks, compare conversion rate to the prior 4-week baseline.
Conclusion
Pricing strategy is one of the highest-leverage levers available to ecommerce operators — and one of the most neglected. Most brands are leaving significant revenue on the table through untested assumptions, unmonitored competitive positioning, and missed bundle opportunities.
The starting point is simpler than most brands think: audit your current pricing, introduce one bundle, add anchor prices to your top 10 products, and run a single price test on your best-seller. The compound effect of those four changes typically adds 8-15% to monthly revenue.
