If you've ever lost a sale to a competitor selling the exact same product, there's a good chance they had the Featured Offer and you didn't. Winning that position consistently comes down to a mix of price, fulfillment, and seller health, and repricing is the tool that keeps your price competitive without you watching it manually every hour.
Here's a clear breakdown of how it all works.
What the Featured Offer (Buy Box) actually is
Amazon now officially calls it the "Featured Offer," though most sellers still say Buy Box. It's the default "Add to Cart" placement on a product detail page, the offer Amazon selects and surfaces to shoppers first.
Multiple sellers can list the same product, but only one gets the Featured Offer at any given moment. Amazon's algorithm rotates that placement among eligible sellers based on a combination of factors. You don't apply for it. You can't pay for it directly. It's an automated outcome based on how your offer stacks up against the competition.
That distinction matters: the Featured Offer isn't just a badge. It drives the overwhelming majority of clicks and conversions on a listing.
The factors that determine who wins
Amazon's Featured Offer algorithm is proprietary, but the company's own Seller Central documentation and the sell.amazon.com blog point to a consistent set of factors:
- Total landed price (your product price plus shipping)
- Fulfillment method and shipping speed (FBA offers tend to perform well here due to Prime eligibility)
- Inventory availability (stockouts pull you out of contention immediately)
- Seller performance metrics (order defect rate, cancellation rate, late shipment rate)
No one outside Amazon knows the exact weights. What sellers can work with is a practical priority order: compete on landed price first, meet shipping speed expectations second, stay in stock third, and keep your performance metrics clean throughout.
One important update as of mid-2026: Amazon posted in Seller Forums (July 6, 2026) that they're "beginning to remove seller eligibility requirements for the Featured Offer," rolling out gradually. Third-party analysis suggests this means seller performance metrics are no longer a hard pass/fail gate, but they still function as weighted ranking inputs. Design your repricing rules to optimize for ranking, not just eligibility.
How repricing actually works in Seller Central
An Amazon repricer monitors the marketplace continuously and updates your price according to rules you define. That feedback loop is the core mechanic.
Amazon's free Automate Pricing tool, available directly in Seller Central, "automatically adjusts your prices in real time" and "responds 24/7" to keep you competitive (sell.amazon.com/tools/automate-pricing). Setup follows a straightforward structure: you create a pricing rule, set the rule parameters, then select the SKUs it applies to (Amazon Seller Central help, reference G201994820). The tool responds to events like a change in the Featured Offer price, so when a competitor moves, your price can move in response automatically.
Amazon's Automate Pricing supports three main rule types:
- Competitive price-based rules (match or beat the Featured Offer price)
- Sales-based rules (adjust price based on sales velocity)
- Business/B2B pricing rules (separate pricing for business customers)
Third-party repricers like Informed Repricer go further, responding to competitor price changes in seconds and applying smart algorithms that can raise your price when conditions allow, not just lower it. The goal there isn't the lowest price; it's the most competitive price that still protects your margin. That distinction is what separates a race-to-the-bottom repricer from a profitable growth strategy.
What a repricer cannot fix
This is where a lot of sellers make mistakes. Repricing only directly influences one dimension of the Featured Offer algorithm: your landed price. It can't:
- Speed up your shipping or switch your fulfillment from FBM to FBA
- Restock inventory you've run out of
- Repair a damaged order defect rate or late shipment rate
- Improve packaging or delivery experience
Aggressive repricing can also backfire. If your min price is set too low or you haven't accounted for actual landed cost (your item price plus shipping, returns, and handling), you can win the Buy Box and lose money on every order. If you sell to business customers, Amazon's B2B pricing rules are separate, applying a standard competitive rule to business pricing tiers without modeling margins correctly is a common error.
The rule: set floors that protect profit before you set rules that chase the Featured Offer.
A practical setup checklist
Before you turn on any repricing rules, run through this sequence:
- Audit your readiness. Check landed price inputs, your fulfillment method and shipping speed, current inventory levels, and your seller health dashboard.
- Define your goal. Are you trying to win the Featured Offer, protect margin on slow movers, clear excess inventory, or balance all three? Your rule logic should match your goal.
- Set min and max boundaries first. A min price floor that reflects your true costs (product cost, fees, shipping, returns) is non-negotiable. Max caps prevent you from pricing yourself out of the range Amazon considers competitive.
- Choose rule logic that targets Featured Offer price events. Competitive price-based rules are the most direct path to Buy Box competitiveness. Layer in sales-based or inventory-pacing logic only after confirming it won't breach your min/max.
- Aim for near real-time response. The faster your repricer reacts to competitor changes, the more time your offer spends in the competitive price band. Amazon's Automate Pricing responds continuously within minutes; purpose-built third-party tools like Informed Repricer respond in seconds.
- Test and review by SKU. Don't set rules and forget them. Watch for unintended price drops, check Featured Offer win rates per category, and adjust your competitive band (not just the price delta).
- Keep the non-price factors tight. Repricing rides on a foundation of inventory coverage, reliable shipping, and clean seller metrics. If those slip, no pricing rule will compensate.
Getting the pricing automation right is genuinely worth the setup time. Amazon's own data shows that sellers using Automate Pricing have seen strong growth, and that's with a free tool that covers the basics. A repricer that also knows when to raise your price, not just lower it, is where the margin protection happens.
