What Is a MAP Violation? What Counts, With Examples

You will see the same thing called a minimum advertised price violation, a MAP policy violation or a MAP pricing violation. They all mean the same thing: a reseller showed your product at a price your MAP policy does not allow. This guide covers what usually counts, the gray areas you have to settle in writing, how to tell a possible violation from a confirmed one, and what to do next. If you need the basics first, start with what a MAP policy is.

What is a MAP violation?

A MAP violation is a public price, or a way of showing a price, that breaks the MAP policy you wrote. Three points follow from that.

It is about the advertised price, not the sale price. Most MAP policies limit the price a reseller displays, not the price a shopper finally pays at checkout (Jungle Scout; SupplyKick). Your policy may be stricter. Read it before you judge anything.

It needs a written policy. If the policy does not say a cart price or a coupon counts, a seller using one has not broken it. The definition is only as clear as the words you published.

It can be deliberate or accidental (42signals). A seller may undercut on purpose to win sales. Or a repricing tool reacts to a competitor and drops the price on its own. Amazon's Automate Pricing, for example, adjusts prices "in response to pricing events like changes in the Featured Offer", within a minimum price, and an optional maximum, that the seller sets (Sell on Amazon). A minimum set below your MAP is enough to cause a violation nobody intended.

Who is bound by it? Dealers who received or agreed to your policy. Unauthorized sellers can still advertise below your MAP, but they never agreed to it, so you handle them differently, as covered below. A policy can cover any channel it names: marketplace listings, Google Shopping ads, retailer and brand websites, email and social posts.

Why it matters: one low advertised price tends to pull others down as sellers and repricers follow it. Dealers who hold your MAP lose sales and margin to the one who does not, and start to doubt the policy is worth following. A product seen everywhere at a discount also starts to look like a discount product.

Three kinds of MAP violation, plus unauthorized sellers

Here is one product, four sellers: three MAP problems and one seller problem.

Illustrative example. Northwind Outdoors (a fictional brand) sells the Trailhead 20L backpack, ASIN B0EXAMPLE1, with a MAP of $49.99. All sellers below are fictional.

Below MAP

The plain case: the listed price is under your MAP. Still confirm variant, pack size and condition (see the checklist below).

Price hidden

Some sellers keep the page price blank and show the real price only in the cart or after the shopper signs in. Policies differ on whether that is "advertising". Brands that count it argue the shopper still sees the low price before buying. The see price in cart guide covers the arguments both ways.

Google Shopping closes this door for retailers who advertise there. Google requires the price in a merchant's product data to "match the price on your landing page and the checkout pages", and tells merchants: "Don't use 'View price in cart'" (Google Merchant Center Help). If a retailer's Shopping ad shows $44.50, that $44.50 is an advertised price.

Below MAP with a deal

The listing shows $49.99, but a coupon, promo code, member price or bulk price brings the number the shopper sees under MAP. On Amazon, Subscribe and Save is a special case: Amazon itself "funds a 5% discount on Subscribe & Save orders of five items or more", and sellers can add 5% or 10% more (Sell on Amazon). Part of that discount is not the seller's choice, which is one reason some policies leave it out.

Unauthorized seller

This one is about who, not how much. A seller not on your authorized list may price at or above MAP and still be a problem: you do not know where the stock came from, and they never agreed to your policy. See unauthorized sellers on Amazon for what brands can and cannot do.

What the evidence for each finding should contain

Whatever the type, a finding is only useful if you can show it to the seller. A solid record has these fields (values illustrative):

In MAPComply, every finding carries these fields, and each price is pinned to your exact variant (matched by ASIN or GTIN first) so a cheaper size or color is not judged against your MAP. The sample report shows the real layout.

Gray areas your MAP policy has to decide

The plain below-MAP listing is rarely the hard call. The hard calls are edge cases the policy never settled. Vendor guides make the same point: whether coupons, cart discounts or Subscribe and Save count depends on how the policy defines "advertised" (SupplyKick).

The right column is one sensible starting position, not an industry rule. Choose your own and write it down.

Two worked cases, both illustrative:

• Bundle. A seller offers the backpack with a water bottle for $54.99. The bottle's own MAP is $14.99, which implies $40.00 for the backpack. Your policy decides whether that is a violation. One way to write it: a bundle may not imply a price below MAP for any item in it.
• Shipping. A seller lists $46.99 plus $5.99 shipping, $52.98 in total. If your policy judges the item price, $46.99 is under MAP. If it adds shipping, it is not.

Possible violation vs confirmed violation

A price under MAP on a screen is a possible violation. It becomes a confirmed one only after you check it. Skipping that check is how brands send notices to sellers who did nothing wrong, and lose their trust.

Common reasons a finding turns out not to be a violation:

• Wrong variant. The listing is a different size or color with its own, lower MAP.
• Wrong pack size. A single unit judged against a 2-pack price, or the reverse.
• Wrong product. A search match that is similar but not yours.
• Currency or region. A price on another country's marketplace, or a geo-targeted price.
• Timing. The page was cached, or the seller fixed it minutes later.
• Allowed by you. An approved MAP sale window, an exemption for that seller, or a brand-funded promotion.

A confirmed violation is one where you have reviewed the evidence, the product is a true match, and a clause of your policy applies to it.

In MAPComply, a finding stays a "possible violation" until you confirm it. Matches that cannot be confirmed as your product are shown as "Couldn't check: match needs review" and never counted.

Before you send a notice:

• The listing is your exact product, variant and pack size
• You have a screenshot or page source, the URL and the time seen
• The price was judged the way your policy says (cart, coupon, shipping)
• No MAP sale window or exemption covers this seller and date
• You know whether the seller is authorized
• You can name the policy clause that was broken

Is a MAP violation illegal?

No. A seller who advertises below your MAP breaks your policy, and possibly the dealer agreement if they signed one. It is not a crime, and you should not describe it as one in a notice.

The legal questions sit with the brand. The Supreme Court held in Leegin (2007) that "vertical price restraints are to be judged by the rule of reason" (Cornell LII). Much earlier, in Colgate (1919), it said a manufacturer "may announce in advance the circumstances under which he will refuse to sell" (Cornell LII).

The FTC's guidance follows the same lines. A manufacturer acting on its own may "deal only with retailers who agree to that policy" and "may stop dealing with a retailer that does not follow its resale price policy". The FTC also warns that "some state antitrust laws and international authorities view minimum price rules as illegal, per se", and it once challenged the MAP policies of five large music distributors as unreasonable (FTC).

So the risk is in how you design and enforce the policy, for example negotiating prices with dealers instead of announcing a policy. Read is MAP pricing legal before you change yours.

What happens to sellers who break MAP?

The consequences are commercial, and your policy sets them. Brands commonly describe an escalation like this (SupplyKick; 42signals):

1. A written warning with a deadline to fix the price
2. A second, firmer notice for no fix or a repeat
3. A hold on shipments or new products, or withdrawn co-op and promotional funds
4. Suspension, then loss of authorized status

Apply the same steps to every seller. Treating one reseller more gently than another undermines the policy.

Amazon is not part of this chain. Its Marketplace Fair Pricing Policy starts from the position that sellers set their own prices, and it acts on prices that harm customer trust, such as prices significantly higher than recent prices or misleading reference prices. It says nothing about manufacturers' minimum advertised prices (Amazon Seller Central). Vendor sources agree that Amazon does not enforce brands' MAP (Jungle Scout; SupplyKick). Unauthorized sellers never agreed to your policy, so brands work on the supply side; Amazon's brand tools help only where there is an IP problem, such as counterfeits.

How to find MAP violations

Checking listings by hand for MAP pricing violations works for a handful of products. It breaks down once you have many sellers per listing, prices that change through the day, and deals that only show in the cart or on a coupon badge.

To see where you stand today, run a free scan on up to five Amazon ASINs or product URLs. You type the MAP and enter your email for the report link. In about a minute you get a shareable evidence report with every seller and price on those listings, and you need no card. The scan uses neutral labels: "Below the MAP you entered", "Price hidden" and "Couldn't check". It is an observation from one moment, not a verdict. The sample report shows what you will get.

For ongoing monitoring, MAPComply runs daily checks on Amazon, Google Shopping and brand and retailer sites, with the evidence above on every finding. Amazon MAP monitoring and how MAPComply matches and checks prices explain the method.

What to do when you confirm a violation

1. Confirm the evidence. Run the checklist above.
2. Check exemptions and MAP sales. Make sure nothing you approved covers it.
3. Check the seller's status. Authorized dealers get your notice process. Unauthorized sellers need the supply-side approach.
4. Send a notice. Keep it factual: the product, the price seen, the MAP, the time, the URL and the clause. The MAP violation letter templates give you first, second and final notice templates. MAPComply drafts the notice with the seller and evidence filled in; you send it from your own email or through Amazon messaging.
5. Re-check. Look again after the deadline. Close the case when the price is back at or above MAP.
6. Track repeats. Keep every sighting by seller, so a seller who slips again is easy to spot.
7. Escalate as your policy says, and the same way for everyone.

The full playbook is in how to enforce MAP pricing.

Your next step: run a free scan on your top five ASINs and see which sellers are below the MAP you enter. Not sure what the result looks like? Open the sample report first. For daily checks with notices drafted for you, plans start at $199 a month: self-serve, no sales call, cancel any time.
