What Is MAP Pricing and Why Every Multi-Channel Seller Needs a Policy

MAP (Minimum Advertised Price) is the lowest price at which an authorized seller is permitted to advertise your product publicly — including on Amazon, their website, and in any media. MAP does not restrict what price a seller can charge privately (in-store to a customer who asks), only what they can display publicly.

MAP is unilaterally set by the brand owner. Under US antitrust law (particularly the Supreme Court's ruling in Leegin Creative Leather Products v. PSKS, 2007), manufacturers can legally establish and enforce MAP policies as long as they do so unilaterally — meaning the brand sets the policy without colluding with retailers or competitors to fix prices.

MAP is different from MSRP (Manufacturer's Suggested Retail Price). MSRP is a suggestion; MAP is a policy with enforcement consequences. A seller can price above MAP freely — they cannot advertise below it.

Without a MAP policy, price competition among sellers carrying your brand destroys margin for everyone — including you if you sell direct on Amazon. A product with a $39.99 MAP that gets undercut to $19.99 by a gray-market importer signals "cheap" to buyers and makes it impossible for compliant retailers to sustain profitable sales.

Price erosion on Amazon is particularly destructive because Amazon's algorithm factors price competitiveness into the Buy Box algorithm. Once one unauthorized seller drops to $19.99, Amazon may suppress your own listing for being overpriced, even if your $39.99 price is the legitimate MAP.

A MAP policy also protects your B2B relationships. US distributors and retailers invest in merchandising, promotions, and sales staff for your brand. If an unauthorized seller undercuts them online, they will stop investing in your brand. MAP is part of protecting the economics of your distribution network.

Setting MAP: include your MAP policy in every authorized reseller agreement as a written condition of the relationship. State the MAP clearly (e.g., "The MAP for Product X is $39.99"). Specify consequences for violation (warning, reduction of credit terms, termination of the reseller agreement).

Amazon enforcement challenges: Amazon itself is not a party to your MAP agreement. Amazon will not enforce MAP on your behalf. If a third-party seller (authorized or not) lists your product below MAP, Amazon will not remove their listing or force a price change.

What you can do: Amazon Brand Registry gives you the right to report unauthorized sellers who may be selling counterfeit or inauthentic versions of your product. If unauthorized sellers undercut MAP, they may not have genuine product — use Brand Registry to report them and request invoice documentation through Seller Central.

Practical MAP enforcement for authorized sellers: monitor your listing price daily using tools like Wiser, Price2Spy, or the free Amazon Price Tracker. When you detect a MAP violation by an authorized reseller, contact them directly with a written violation notice. First violation: warning. Second violation: reduce order priority. Third: terminate the reseller agreement.
