No Buy Box and no competitor: why Amazon hides your offer, and what it does to your ads

You open your product page and the Add to Cart button is gone. In its place is a link that says See All Buying Options. You are the only seller. Nobody undercut you, yet sales are falling. A few days later the ads on that product stop spending, and the budget hasn't changed.

This shows up most after a big sale. Prime Big Deal Days runs October 6 and 7 on Amazon.com, and Canada is one of the countries taking part. Other retailers run their own fall sales around the same days. When those discounts land, Amazon can stop featuring your price. Here is what is happening and what to do.

What Amazon is doing when it hides your offer

The Buy Box is the box on a product page with the Add to Cart and Buy Now buttons. Amazon calls it the featured offer. When several sellers offer the same product, Amazon picks one to feature. Being the only seller does not guarantee it. Amazon compares your total price (price plus shipping) with a set of reference prices. If yours is higher, Amazon can decline to feature any offer at all. The listing stays live, but shoppers need an extra click to buy. We call this suppression.

Amazon's pricing documentation names the reference prices:

• Competitive External Price. The lowest price recently found at another reputable retailer outside Amazon. Amazon does not say which retailer. It can also work from the per-unit price of another pack size, or from a near-identical product sold under another brand.
• Average selling price. What customers paid on Amazon over the last 60 days. Prices during promotions such as Lightning Deals are left out.
• List price. The suggested retail price supplied for the product. Amazon notes that products are usually not sold above it, so a price above your list price can cost you the featured offer.

The same documentation says an offer flagged this way cannot be featured at its current price, whatever competitors do.

Suppression or a reseller? Tell them apart in five minutes

A reseller taking your Buy Box needs a different fix, so confirm which problem you have first.

In our experience, nothing else in Seller Central flags it. The listing shows as active, with no errors. Pricing Health is where Amazon states the reason in words.

The cost that hides in your ad account

Sponsored Products are the pay-per-click ads that place your product in Amazon search results. Amazon's advertising guide says that if your product isn't presenting the featured offer, the ad will not display. Suppression switches your ads off too.

In the accounts we run, spend on the suppressed product drops to exactly zero and stays there. No campaign is paused. No budget ran out. The rest of the account keeps spending, so the total looks only a little soft.

Two habits help. First, compare each product's daily ad spend with the whole account's. One product at zero while the others spend is a featured offer problem until proven otherwise. A whole account at zero points to billing or budgets. Second, if a campaign advertises only the suppressed product, point it for now at a sibling that still holds its Buy Box, such as another pack size, with the same keywords. Campaigns that include several products shift spend to the others on their own. Give the moved ads a couple of days before you judge them, since the order value changed.

Find the price Amazon wants, then decide

Don't guess the number. Pricing Health shows the reference price you were compared with. If you or your developer use the Selling Partner API (Amazon's connection for seller software), one call returns the featured offer expected price: the price at which your offer can be featured. It works on up to 40 SKUs (your own product codes) at a time.

Then do the math. Sometimes the gap is a few cents and matching is obvious. Sometimes the reference sits below what the product costs you to make and ship through FBA (Fulfillment by Amazon, where Amazon stores and ships your stock). In our experience, a price that low usually comes from a clearance sale, another pack size or a lookalike product. Matching it means selling at a loss. Contest it with Seller Support, starting from Pricing Health, and keep your ads on a sibling product while you wait.

Check your list price too. We often find list prices set at launch and never updated, sometimes below the selling price. That alone gives Amazon a reason to stop featuring you.

Hold one price, market by market

Amazon says it reviews which outside retailers it compares against for each country. A Canadian retailer's flyer price is what can set your reference on Amazon.ca, and a US retailer's markdown is what matters on Amazon.com. In our experience, a US sale does not lower your Amazon.ca reference by itself. The trap is automation: if your Amazon.ca prices follow your US prices, a US event price can carry north, pull down your Canadian average, and make your normal price look high once it returns. Set each marketplace's price and list price in its own currency, on purpose.

The brands that rarely see suppression keep one price across channels. If a wholesale account clears your product at a deep discount, Amazon can see it. Before an event, agree with retail partners on how deep and how long. On Amazon, use Amazon deals for event discounts and leave your base price alone, since deal prices stay out of the average selling price.

No Buy Box with no competitor is Amazon telling you your price looks high somewhere. This week, open Pricing Health, read the reference price, check each product's ad spend against the account, and decide product by product whether to match or contest.
