Dynamic pricing is one of the most powerful tools in the e-commerce arsenal. Yet many managers and store owners approach it with enormous hesitation — either avoiding it altogether, or implementing it in ways that generate losses instead of profits.

Why the reluctance? A number of harmful myths have grown up around pricing automation, paralyzing decision-making and leading to the loss of real profit. McKinsey estimates that companies implementing intelligent pricing strategies achieve EBIT margin growth of 2–7 percentage points — without increasing their advertising budget or changing their product range. Forrester Research, meanwhile, indicates that pricing strategy errors account for the loss of up to 30% of potential revenue in a typical online store.

Instead of guessing based on gut feelings, let's look at hard data and the principles of sales psychology. Here are the 5 biggest myths about dynamic pricing in e-commerce that are destroying your margin — and how to debunk them.

Myth 1: "You Always Need the Lowest Price to Sell"

This is probably the most costly myth in all of e-commerce. Many sellers believe that dynamic pricing is simply a "race to the bottom" — a battle where the winner is whoever sacrifices their margin the most.

The reality

Behavioral research consistently shows that customers don't buy the cheapest option — they buy the "safe" option. The lowest price in a comparison engine often triggers distrust: "Why is it so much cheaper? Is it genuine? Will it arrive on time?" This is a phenomenon known in pricing psychology as the Veblen effect in its e-commerce form — a price that's too low signals low quality.

The best universal strategy for most product ranges is to position yourself 2nd or 3rd on price among your key competitors. Why does this work?

• A customer who sees three offers intuitively treats the middle one as a "sensible compromise" (the price anchoring effect).

• The store in 1st place on price acts as a traffic generator (price leader) for the entire category, but typically generates the lowest margins.

• The store in 2nd–3rd place captures customers who "want to save money, but not at the cost of risk" — and that's a large, loyal group.

Competing on price alone only makes sense for products serving as price leaders — bestsellers that drive traffic to the store. On long-tail products and premium products, you should be making money, not wasting your margin in a race you can't win.

Myth 2: "Any Price Increase Will Immediately Drive Customers Away"

Fear of losing customers is the main reason stores avoid testing higher prices for years on end. It feels as though customers are mercilessly sensitive to every cent, and any price increase means the permanent loss of a buyer.

The reality

Professors Robert Dolan and Hermann Simon demonstrated in a now-classic study that a 1% price increase at constant sales volume translates to an average 11% increase in operating profit — that's the pricing leverage effect that most managers never consider.

The secret lies in the small steps method (incremental pricing):

1. Raise the price by 1–2% on a product that's already selling well.

2. Monitor volume for 2–3 weeks — in most cases it won't move.

3. If sales drop significantly — revert to the previous price. Customers will return quickly, because the change was minimal.

4. If sales remain stable — consider another step of 1–2%.

Importantly, consumer price sensitivity is strongly nonlinear and asymmetric. A customer who was buying a product at $199 will rarely notice a move to $203. But they will certainly notice a move from $199 to $249. That's why psychological thresholds matter: $49 / $99 / $149 / $199 / $249 / $299 / $499 — and you should never cross them in a single move.

Furthermore, behavioral economics research points to the endowment effect — a customer who has previously bought from your store is significantly less sensitive to a price increase than a new buyer. This means your loyal customer base is your natural "pricing cushion."

Myth 3: "Every Store That's Cheaper Is Your Direct Competitor"

You see in a price comparison engine that an obscure store is offering your bestseller at 10% less. In a panic, you lower your price to match them. You've just surrendered part of your margin to someone who wasn't a threat to you in the first place.

The reality

Not every store with a lower price actually takes customers away from you. Why? Because price is just one of a dozen or more factors in a purchase decision. A store with the cheapest offer can deter buyers at entirely different stages of the funnel:

Instead of racing to the bottom to match the weakest market players, you need to identify your real competitors — those who are genuinely taking orders away from you. How?

• Analyze the correlation between price changes at specific stores and your own sales volume.

• Monitor stores that have a similar level of reviews, organic reach, and delivery offer.

• Apply selective repricing rules — react only to price changes from real competitors, and ignore the rest.

Myth 4: "A Price Cut Is the Only Way to Save a Product That Isn't Selling"

You have stock sitting in the warehouse that nobody's buying, so you cut the price. When that doesn't work, you cut it again. The margin is long gone, and the product still sits there. Sound familiar?

The reality

If a dramatic price cut doesn't drive a sales increase, that's a warning signal: price is not the problem at all. In e-commerce there are several hidden "conversion killers" that are far more dangerous than poor pricing:

Visibility problems:

• The product doesn't appear in the store's internal search (tagging errors, missing synonyms).

• Low rankings in Google Shopping due to a weak product feed.

• Absence from the relevant categories and filters.

Content problems:

• Product description copied from the manufacturer (duplicate content, no uniqueness).

• Low-quality photos that don't show the product in use.

• No answers to key customer questions (dimensions, compatibility, material).

Purchase cost problems:

• Prohibitive shipping costs for low-value products.

• No deferred payment options for higher-priced products.

How to diagnose the real problem:

1. Check the organic traffic to the product page — is anyone visiting it at all?

2. If yes — examine the conversion rate and compare it with the category average.

3. If conversion is low — check heat maps and session recordings (e.g. Hotjar).

4. Only once you've ruled out the above — test the price.

Myth 5: "Dynamic Pricing Is a One-Time Setup — Set It and Forget It"

You've bought a repricing system, set a rule saying "be 1% cheaper," and consider the matter settled. The algorithm is working; you don't need to be involved.

The reality

No price is optimal forever. The e-commerce environment is a dynamic system in which dozens of variables evolve simultaneously:

• Seasonality — the price elasticity of the same product is different in December than in July.

• New entrants — a new competitor with an aggressive pricing strategy can reshape the landscape of a category within weeks.

• Competitors' ad campaigns — during their Black Friday push, your rules may generate suboptimal decisions.

• Shifts in consumer behavior — inflation, recession, trends — all of these move price sensitivity thresholds.

• Changes in your own costs — rising procurement, logistics, or fulfillment costs require regular updates to your pricing rules.

The human brain has a natural tendency to incorrectly attribute sales declines solely to price, when entirely different factors may be to blame. A good dynamic pricing system needs to account for this.

How to implement continuous improvement of your pricing strategy:

1. Interval testing — alternately raising and lowering prices in defined cycles allows you to measure actual demand elasticity.

2. Regular rule reviews — at minimum once per quarter, verify that your pricing rules still reflect market realities.

3. Time-based segmentation — apply different pricing thresholds at weekends, during peak evening shopping hours, or during email campaigns.

4. Anomaly monitoring — any sudden spike or drop in conversion should trigger an alert and an analysis.

Bonus: What Repricing Tools Won't Tell You — Pricing Psychology in Practice

No dynamic pricing software can replace an understanding of buyer psychology. Here are three mechanisms worth building into your strategy:

Price endings (.99 and .95) — classic research by Schindler and Kibarian shows that a price of $199 is perceived as significantly lower than $200, despite the difference being just $1. This effect is strongest at the first digit ($199 vs $200) rather than at later digits ($199 vs $198).

The anchoring effect — if you display a crossed-out higher price alongside the current price, the perceived value of the product increases and sensitivity to the current price decreases. Dynamic pricing management should include intelligent management of "before" and "after" prices.

Bundling and perceived savings — instead of lowering a product's price, offer a bundle with a complementary product at an "attractive" combined price. The customer perceives it as a win; you keep the margin on both items.

Summary

Dynamic pricing is not about blindly chasing the lowest number on the market. It's about the skill of combining data, psychology, and continuous experimentation — from intelligent positioning at 2nd–3rd place on price, through the method of small incremental increases, to deliberately ignoring irrelevant competitors.

Key principles to remember:

• Lowest price ≠ highest sales. The 2nd–3rd position in a price ranking often generates higher profit than being the price leader.

• Small price increases are nearly invisible to customers, but very visible on the profit and loss statement.

• Not every cheaper store is your competitor. React only to the moves of players who are genuinely taking orders away from you.

• A slow-selling product is not always a pricing problem. Diagnose visibility and content first.

• Dynamic pricing is a continuous process. The market changes — your pricing rules need to keep up.

Stop being afraid to test higher prices, and stop surrendering your margin to competitors who have nothing to offer but the zeroing out of their own profits. Your margin is too valuable to give away out of fear of a myth.
