A MAP policy — Minimum Advertised Price — is a unilateral policy issued by a brand that sets the lowest price at which authorized resellers are permitted to advertise the brand’s products. On Amazon, that includes the price shown on the product detail page, in search results, and in any external marketing. MAP does not govern the price at which a product can ultimately be sold (that would raise antitrust issues); it governs the advertised price only. A MAP policy is not enforced by Amazon — it is a brand-owned policy, and enforcement falls on the brand.
Why It Matters for Sellers
For brand owners, MAP is the primary defense against a price race to the bottom on Amazon. Once one authorized reseller drops the advertised price by a few dollars, others follow to hold the Buy Box, and within days a well-priced brand can lose 10-20% of its price floor with no way to recover without alienating the entire channel. MAP protects the brand’s suggested retail price, keeps authorized resellers profitable, and preserves margin for brick-and-mortar partners. For resellers, understanding a brand’s MAP policy determines whether you can even list a product profitably — undercutting MAP can result in loss of authorized-reseller status and, on Amazon, disciplinary action from the brand.
How MAP Enforcement Works on Amazon
- Brand publishes MAP policy — a formal document defining the minimum advertised price per SKU, effective dates, and consequences for violation.
- Authorized reseller list — the brand maintains an approved-seller roster; only these sellers are permitted to list.
- Monitoring — the brand (or a service on their behalf) monitors advertised prices across Amazon, other marketplaces, and reseller websites.
- Violation detected — a reseller advertises below MAP.
- Enforcement — the brand issues warnings, requires the price to be corrected within a set window (often 24-72 hours), and escalates repeat offenders by pulling their authorized status, cutting off supply, or filing an Amazon complaint against unauthorized sellers.
Amazon itself does not enforce MAP because MAP is between the brand and its resellers. What Amazon does do is honor Brand Registry complaints when a MAP violator is also an unauthorized seller.
MAP vs MSRP vs Sale Price
| Term | What It Governs | Set By |
|---|---|---|
| MAP (Minimum Advertised Price) | The lowest price advertised publicly | Brand |
| MSRP (Manufacturer’s Suggested Retail Price) | Suggested sale price | Brand (advisory only) |
| Actual sale price | Price the customer pays at checkout | Retailer |
A brand can legally set a MAP; a brand generally cannot legally dictate the price at which a product is finally sold (that would be resale price maintenance).
Common Mistakes
- Assuming Amazon will enforce a MAP policy — they will not; the brand must monitor and enforce.
- Publishing a MAP policy without a monitoring cadence to actually catch violations.
- Enforcing inconsistently, which weakens the policy legally and practically.
- Failing to combine MAP monitoring with unauthorized-seller enforcement — unauthorized sellers rarely honor MAP.
