What the Buy Box is now called, and why it still decides sales

Amazon now calls the Buy Box the Featured Offer. It sits in what Amazon's own seller blog calls the Offer Display: the box on the detail page with the price, the delivery promise and the Add to Cart and Buy Now buttons. Every other seller on the same ASIN moves into the Other sellers on Amazon list below it.

Most shoppers never open that list. They buy from whichever offer is featured. So on any ASIN with more than one seller, the Featured Offer is the difference between selling and being listed.

It also controls your advertising. SalesDuo quotes Amazon Ads documentation saying Sponsored Products ads can stop generating impressions when your SKU does not hold the Featured Offer. A brand that loses the box to a reseller can watch ad impressions fall the same day, with no change in bids.

What changed in July 2026: no more eligibility gate

For years the Featured Offer worked in two stages. First Amazon screened sellers on metrics such as Order Defect Rate, Late Shipment Rate and cancellation rate. Only sellers who passed were ranked for the box.

EcomCrew reported on July 7, 2026 that Amazon is removing that first stage. All offers are now ranked directly, with a global rollout that started in July and is expected to finish by the end of 2026. Sellers did not need to opt in. SalesDuo, updated in September 2026, describes the same change.

This matters in two directions. Sellers who used to be locked out on a weak metric can now compete. And brands that relied on the gate to keep sloppy resellers away from their listing have lost that protection. Several popular 2026 guides still describe the old pass or fail thresholds as hard rules, so treat any checklist that says you are disqualified at a single number with care.

The four inputs Amazon says it weighs

Amazon does not publish weights. Its April 2026 seller blog names four areas, and every serious guide we read lands on the same list. Being considered is not the same as being chosen: the box goes to the offer that is strongest across all four.

• Price: Amazon says Featured Offer prices are commonly at or below the lowest priced alternatives, and it compares total price including shipping, not item price alone.
• Delivery: fast, free shipping and a narrow, certain delivery date are more likely to be featured. Amazon states that fulfilling orders yourself can be just as effective as FBA when the promise is strong.
• Order experience: the right item, undamaged, authentic, unexpired and charged correctly. Amazon points sellers to Voice of the Customer and Account Health to check this.
• Stock: an out of stock offer cannot be featured. Running dry hands the box to whoever still has units.

Why your listing shows See options instead of Add to Cart

Sometimes nobody wins. Amazon's seller blog says the See options button appears when no offer can be featured, and gives three reasons: the item is out of stock, the price is too high, or the price is too low. A very low price can trigger a suspected pricing error check that asks you to confirm the price.

Too high usually means too high against Amazon's reference prices, which include competitive prices Amazon sees outside its store. Amazon shows these in Manage All Inventory under View reference and business prices, and in Pricing Health. Third party tools suggest rules of thumb such as staying within 10 percent of the 90 day Buy Box range. Those are vendor heuristics, not Amazon policy.

The fix is not always to cut price. If your price is higher on Amazon because a retailer or your own site is running a discount, the cheaper fix may be the outside price, not your Amazon margin.

Brand owners and resellers need different answers

Almost every guide on this topic is written for resellers competing on a shared listing. Brand owners have a different problem. On a private label ASIN, a healthy brand should hold close to all of the Featured Offer share. When it does not, the cause is usually one of three things.

First, an unauthorized seller is undercutting you, often with grey market or old stock. Second, your own stock ran out and someone else filled the gap. Third, Amazon Retail is buying your product through a distributor and selling it as a first party offer. Lowering your price against the first one trains the market to expect a lower price and erodes the margin you built the listing on.

For brands, the durable fix is enforcement and distribution control: Brand Registry, a clean authorized reseller list, MAP terms in your distribution agreements and test buys that document violations. Repricing is a short term bandage, not the plan. Our brand protection service handles monitoring and takedowns, and full-service clients get it as part of the plan.

Worked example: what a lost Buy Box costs (illustrative numbers)

Take an illustrative brand selling a $30 supplement. Its variable cost per unit, including product, FBA fee, referral fee and ad cost, is $22, so it keeps $8 a unit. It sells 1,500 units a month while holding about 95 percent of the Featured Offer.

A reseller lists the same item at $27. Featured Offer share drops to 50 percent. Sales from the brand's own offer fall to roughly 790 units, and contribution falls from about $12,000 to about $6,300 a month. Sponsored Products impressions also drop on the hours the brand does not hold the box.

Option one is to match at $27. The brand wins share back, but keeps only $5 a unit: about $7,100 a month on 1,425 units, and every customer now sees $27 as the price. Option two is to remove the reseller. If that takes four weeks and restores share, the brand loses about $5,700 once instead of $4,900 every month forever. That is the math behind enforcement first.

Playbook: 5 steps to win the Amazon Buy Box back

Run these steps in order. Each one names who owns it, where to find it and which number shows it worked.

• Ops lead, Business Reports: open Detail Page Sales and Traffic by Child Item and sort by Featured Offer percentage. List every ASIN below 90 percent. Metric: the list of ASINs under 90 percent shrinks week over week.
• Ops lead, the listing itself: for each flagged ASIN, open Other sellers on Amazon and note who holds the box, their price, condition and delivery date. Metric: every flagged ASIN has a named cause (price, delivery, stock, reseller or Amazon Retail).
• Pricing owner, Manage All Inventory and Pricing Health: check reference prices and set a price floor from margin, not from the competitor. Fix outside prices that are pulling the reference down. Metric: no ASIN shows See options for price reasons.
• Inventory planner, FBA Inventory and restock reports: keep at least the lead time plus a safety buffer on hand for every top seller, so stock never hands the box away. Metric: zero stockout days on top ASINs.
• Brand manager, Brand Registry: test buy from unauthorized sellers, document violations and report them, then tighten distribution terms. Metric: unauthorized seller count on your ASINs falls and your Featured Offer percentage returns above 95 percent.

When this advice does not apply

If Amazon Retail sells the same item, you are not competing on equal terms, and price cuts rarely win the box for long. The better question is whether to sell to Amazon through Vendor Central or stop the distributor supplying it.

If you resell a commodity item with dozens of sellers, enforcement is not an option and you are in a pure price and delivery race. A disciplined repricer with a margin floor is the right tool there. And if your product barely sells, a full management plan may cost more than the share you would win back. Start with the free audit and fix the basics first.
