Amazon price error or misread? How to spot a wrong price before it reaches your eBay listing

What is an Amazon price error, and how is it different from a misread?

An Amazon price error is an offer listed at a price that is clearly wrong, usually far below its normal level and sometimes far above it. A misread is different: the Amazon page is correct, but your price tracker has picked up the wrong number. For an eBay seller who reprices from Amazon, both have the same result. A wrong cost goes into your formula, and a wrong price goes onto a live listing.

A price that is too low on eBay sells quickly and loses money on every order. A price that is too high stops sales. Either way, the fix is the same: check every reading against what you know about the product before letting it change anything.

What causes genuine Amazon price errors?

Amazon does not publish why individual prices go wrong, but the common causes are easy to understand.

• Seller mistakes. A third-party seller types the wrong price, misses a digit or uploads the wrong file.
• Repricing tools going wrong. Sellers' own software can chase each other down, or react to a bad input.
• Placeholder prices. A seller out of stock may set a very high price rather than remove the offer.
• Wrong product data. A price for a single unit attached to a multipack listing, or the reverse.
• Short-lived deals. A real deal can look like an error, and it ends just as suddenly.

Whatever the cause, such prices tend not to last. What happens to orders placed at an obviously wrong price is set out in Amazon's own Conditions of Use and Sale; read them rather than relying on anyone's summary.

What causes a tracker to misread an Amazon price?

Misreads are often more common than genuine errors, because an Amazon product page carries many numbers besides the price.

The caption case deserves a mention of its own. When a page has no buy box price at all, a careless reader can grab the first number that looks like a price from somewhere else on the page. The result can be any figure at all. A page with no price should produce no reading, not a guess.

Why wrong low prices do the most damage

A wrong high price costs you sales quietly. A wrong low price costs you money loudly, because eBay buyers find underpriced items quickly, and every order placed before you notice is one you either fulfil at a loss or cancel. Cancelling has its own cost: a seller-cancelled order counts as a transaction defect under eBay's seller performance standards. The best protection is to stop the wrong price reaching eBay in the first place, rather than cleaning up after it.

Sale events make this worse. During big events, pages change format, deal badges and countdown timers appear, and more prices move at once. That is exactly when a tracker is most likely to misread, and when a genuine short-lived deal is most likely to be mistaken for a lasting price. Tighten your checks during events, not loosen them.

How do you spot a wrong price before it goes live?

The checks that catch both errors and misreads are the same.

1. Compare with the product's history. A reading far outside the normal range is suspect until confirmed.
2. Set a swing limit. Hold any change bigger than a set percentage from the last good reading.
3. Set a floor and a ceiling. Never push an eBay price below your minimum profit or above a sensible maximum.
4. Check the currency and address. Reject readings in the wrong currency or for the wrong delivery country.
5. Check the condition and seller. A switch to a used offer or an unknown seller is a reason to look again.
6. Re-read before acting. A genuine price change is still there on the next reading; a glitch often is not.

What a sensible swing limit looks like

There is no correct number for everyone. Products that normally move a few per cent a week can use a tight limit; products that move a lot need a wider one, or they will be held constantly. Start with a limit that would have caught last month's worst bad readings without holding the normal ones, then adjust. The aim is a review queue small enough that you actually look at it every day.

What does a wrong price cost on eBay?

A hypothetical example

Example: suppose a pack of 12 batteries normally costs £9.00 and your eBay price is £12.27, from a 20% markup and a hypothetical 12% fee allowance. One reading picks up the unit price, 75p per battery, as the item price. Without a check, the formula sets your eBay price at about £1.02. In the hours before the next reading, buyers notice and order. Each order costs you £9.00 plus fees and returns about £1.02. With a swing limit, the reading is held for review as a 92% drop, you open the page, see the unit price, and the live price never changes.

A misread in the other direction, such as a struck-through was price of £19.99 read as the cost, pushes your eBay price to about £27.26. Nobody buys, and the listing loses its sales momentum until the next good reading. Less painful than the first case, but still a cost.

What should you do when you find a wrong price?

• Do not push it. Keep the eBay price at its last good level until a reading you trust arrives.
• Check the page yourself. Open it at your usual postcode, with the right account, and look at the buy box.
• Find the cause. Was it a genuine Amazon error, a misread, a variation, a currency or a condition change?
• Fix the cause, not just the reading. If your tracker reads unit prices, it will do it again on other products.
• Check recent sales. If a wrong price did go live, look at orders taken during that time and deal with each one honestly.

How do repricers guard against wrong prices?

A repricer that pushes every reading straight to eBay is only as good as its worst reading. Good ones put guards between the reading and the push. Dropizon's guards check every push: a currency guard, a price circuit breaker with a floor, a ceiling and an optional swing limit, and holds that wait for one-click review, with a reason recorded for every push and every hold. The documentation describes each guard, and the Subscribe and Save price guide covers one of the most common misreads in detail.

Whatever you use, the principle does not change: sourcing from Amazon is governed by eBay's rules as well as your own checks. eBay allows dropshipping from a wholesale supplier, but listing an item and then buying it from another retailer or marketplace that ships directly to your buyer is not allowed under eBay's drop shipping policy. You stay responsible for delivery within your stated time and for your buyer's satisfaction.

A wrong-price checklist

• Set a floor, a ceiling and a swing limit on every listing.
• Compare each reading with the product's normal range before using it.
• Reject readings in the wrong currency, for the wrong address or for the wrong condition.
• Make sure a page with no price produces no reading.
• Re-read big changes before acting on them, at your usual postcode and account.
• Review your hold queue daily, release the good readings and fix the causes of the bad ones.
• Never build a listing on a glitch or a deal that is unlikely to last.
