Screenshot standards for Amazon, Walmart Marketplace, Target Plus, and Best Buy Marketplace
You catch a product listed below MAP, send a screenshot to the seller, and hear back: “That wasn’t our offer.” The image showed a low price. It didn’t show whose price it was.
That gap between spotting a pricing issue and proving it exists on every marketplace where your products sell — Amazon, Walmart Marketplace, Target Plus, and Best Buy Marketplace.
An effective MAP violation screenshot connects four things: the exact product, the seller responsible for the offer, the advertised price with its full conditions, and the time of observation. The core steps for capturing that are close to identical across every marketplace. Where they genuinely differ is in how each one shows you who is selling a product, and how each one can quietly discount the price on screen without the seller having touched it.
This guide sets one documentation standard, then flags where a specific marketplace breaks from it. Sections 2 and 4 have a subsection for each platform; the rest apply across all four. It’s also the standard we apply at Brand Alignment when we run this monitoring for clients — a screenshot that doesn’t hold up under a seller’s pushback is a screenshot that stalls the whole enforcement process.

1. Confirm the Product and the Applicable MAP Price
Start with your brand’s MAP schedule effective on the observation date — not the platform’s crossed-out reference price, and not the manufacturer’s suggested retail price (MSRP). MAP and MSRP are not the same number, and platforms often display a struck-through price that reflects neither.
Match the selected model, size, color, pack quantity, and condition against your product records before you treat anything as a MAP violation. Do not compare a used, refurbished, or multipack offer against a threshold set for a single new unit.
Check for approved promotional windows and your policy’s treatment of shipping charges, coupons, and cart pricing. Until all of that is verified, classify the observation as a potential violation, not a confirmed one.
Product identifiers by channel
- Amazon: the ASIN for the exact variation. Where variations exist, use the specific child ASIN, not the non-buyable parent ASIN.
- Walmart Marketplace: the Walmart Item ID, plus your internal SKU for cross-reference.
- Target Plus: the TCIN (Target’s internal item number), visible in the product URL after “/A-“.
- Best Buy Marketplace: the Best Buy SKU number shown on the product page.
2. Identify the Seller
Open the live product page rather than relying on a search-result thumbnail, and inspect the specific offer you are documenting — not just the default one shown. On every platform below, a low price and a seller name only count as evidence when you captured them together, for the same offer. Misattributed seller identity is one of the more common ways a notice gets challenged later — it hands the recipient an easy, factual objection, which is exactly why this step gets its own section here.
Amazon
Locate “Sold by” in the purchase area. Do not confuse it with “Ships from” — a product can be sold by a third-party seller while Amazon handles fulfillment, so “Ships from Amazon” alone does not make Amazon the seller.
Open “Other sellers on Amazon” or the buying-options link, since Amazon displays additional offers outside the Featured Offer (the Buy Box). Capture the seller’s name, price, condition, and shipping charge together, and save the seller profile URL and seller ID separately. Keep Amazon Retail offers and third-party offers in separate records — a screenshot of one seller’s price should never support a notice addressed to another.
Walmart Marketplace
Walmart labels sellers as “Sold by” or “Sold and shipped by.” Walmart can also warehouse and ship inventory for Marketplace sellers, so Walmart fulfillment does not make Walmart the seller.
Click the seller’s name to preserve the seller profile URL and business information, and check “More seller options” rather than stopping at the main purchase area — a seller’s offer can be valid even when it isn’t shown in the main Buy Box. Never pair one seller’s name with another seller’s price.
Target Plus
Target Plus is invite-only: Target vets every partner before it can list, and most Target Plus items are single-seller listings rather than a competitive Buy Box. That changes the check — there usually is not an “other sellers” panel to open.
Look for “Sold and shipped by [Seller Name]” with a small Target Plus badge on the product page, directly under the price. If that line is absent, the item is sold and shipped by Target itself.
Occasionally more than one Target Plus partner lists the same physical product as separate listings under separate TCINs. If you are tracking one seller specifically, confirm you have the right TCIN, not just the right product name.
Best Buy Marketplace
A caveat before the mechanics: Best Buy’s U.S. marketplace launched broadly on BestBuy.com in August 2025 (Best Buy Canada’s has run since 2016), so the workflow below is newer and less battle-tested than Amazon’s or Walmart’s. Confirm current behavior on a live listing before locking this into a permanent process.
Look for “Sold and Shipped by [Seller]” directly above the Add to Cart button. If that line is absent, Best Buy is the seller. Check “More Buying Options” (or the equivalent link on the listing) for competing offers from other Marketplace sellers on the same product, the same way you would check Amazon’s other-sellers panel, and click the seller’s name to open more seller information.
A note on price-comparison sites: Google Shopping and similar comparison engines are where a lot of violations surface first, but they are not marketplaces — they redirect you to checkout on the seller’s own site or on one of the four platforms above. Treat a comparison-site listing as a lead: click through and document the offer on whichever platform it actually lands on, using that platform’s section above.
3. Take a Screenshot That Preserves Context
Use a desktop browser and begin with a broad view showing the product title, selected variation, price, seller name, and the browser address bar.
- On Windows: press Windows + Shift + S to open the Snipping Tool overlay, select the relevant area, and save the capture as an image file rather than leaving it only on the clipboard.
- On a Mac: press Shift + Command + 4 to capture a selected area, or Shift + Command + 3 for the entire screen. Include the address bar and offer details in the selection.
Add a close-up when useful, but keep the broader screenshot too, and don’t shrink the page until important text becomes unreadable. When the evidence doesn’t fit one view, save numbered screenshots with overlapping details (product page, seller offer, seller profile) rather than assembling them into a composite. Reopen every saved image afterward and check that it’s actually legible.
4. Watch for Promotional and Membership Pricing
A lower displayed price doesn’t always mean the seller set that price. Every one of these four platforms can layer its own discount on top of — or instead of — what the seller actually charges, and the mechanics for that differ by platform. This is often where in-house teams get tripped up, so it’s worth a second look before a notice goes out on a discount that turns out not to have been the seller’s doing.
Amazon
Amazon can fund discounts or coupons on selected third-party offers while paying the seller based on the seller’s original listed price. Capture any visible coupon, discount label, and eligibility requirement, and document the page before and after applying a promotion where possible. An offer shown at $100 with a $10 coupon needs more context than a screenshot showing only the $90 result.
Walmart Marketplace
Walmart-funded incentives can lower the price a customer pays while leaving the seller’s net payment unchanged; Walmart specifically advises sellers to exclude MAP items from that program, but capture the displayed price and ask the seller to verify rather than assuming either way. Separately, distinguish Walmart Cash — promotional currency redeemable on a future purchase — from an immediate price cut. An item shown at $100 with an offer to earn $10 in Walmart Cash is not the same thing as a $90 advertised price.
Target Plus
Target’s own published terms exclude items sold by Target Plus partners from both Target Circle offers and Target’s price-match program. That’s a real structural difference from Amazon and Walmart: a discounted price on a Target Plus listing is more likely the seller’s own listed price than a platform-funded coupon. Still record whether you were signed into a Target Circle account during the observation, since Target personalizes some pricing and promotions by account and location. Public documentation on Target Plus pricing mechanics is limited, so if this becomes a recurring question, verify current behavior against Target’s Target Plus partner terms rather than treating this section as exhaustive.
Best Buy Marketplace
My Best Buy membership rewards accrue on Marketplace purchases the same as on Best Buy’s own inventory, but reward points are a post-purchase credit, not a price reduction visible on the listing — don’t treat them as part of the advertised price. Confirm separately whether any discount shown on a Marketplace listing is a Best Buy promotion or the seller’s own price; given how new the U.S. Marketplace program is, this is worth a direct check rather than an assumption.
5. Document Cart Pricing Without Losing Attribution
When your MAP policy requires reviewing cart pricing, add the specific seller’s offer to the cart and verify the seller and variation again at that stage — capture the item-level price and discount breakdown, not an unrelated whole-cart total. This applies the same way on Amazon, Walmart, Target Plus, and Best Buy. Walmart in particular runs a “MAP Cart” setting that can reveal a price only once an item is in the cart rather than on the public product page, so check cart pricing there even when the listed page price looks compliant.
Evaluate any cart-stage discount under your written policy rather than automatically counting, or automatically disregarding, every coupon as a violation.
6. Record the Time and Shopping Conditions
Log the full capture date, time, and time zone with every screenshot, using a synchronized device clock. Treat that clock as supporting context, not independent proof of authenticity, and preserve any capture logs your monitoring system provides.
Every platform here can show a different price to different shoppers based on location, delivery option, and account status. Record the marketplace or region, currency, delivery ZIP code or selected store, and whether you were signed in — and if so, under what membership status: Prime, Walmart+, Target Circle, My Best Buy, or none. Keep those conditions consistent across follow-up checks, and if an offer changes between screenshots, record the change honestly rather than combining observations from different times as though they show one unchanged offer.
7. Preserve Originals and Organize the Evidence
Save an unedited original of every screenshot, and create separate copies for highlighting, cropping, or redacting personal information before sharing. Never alter the displayed price, seller name, or page content to make the evidence clearer — add explanations in accompanying notes instead.
Use a consistent naming convention that includes the platform, such as:
AMZ_ASIN_SellerID_YYYYMMDD_HHMMSS_TimeZone_01.pngWMT_ItemID_SellerID_YYYYMMDD_HHMMSS_TimeZone_01.pngTGT_TCIN_SellerID_YYYYMMDD_HHMMSS_TimeZone_01.pngBBY_SKU_SellerID_YYYYMMDD_HHMMSS_TimeZone_01.png
Store the screenshots with the product URL, seller profile URL, applicable MAP schedule, capture details, and review notes, and keep seller communications in the same case record so another team member can reconstruct what happened. Protect account names, delivery addresses, and other unnecessary personal information in any shared copies. When you recheck an offer, save a new observation instead of overwriting the original — a screenshot documents a moment, not an uninterrupted price history. This is the same structure a monitoring process needs before an observation is ready to support a seller notice.
8. Use the Evidence for the Right Enforcement Process
Before contacting a seller, review the complete record for product accuracy, seller attribution, promotional context, and policy applicability. For an authorized seller, a notice should identify the product, the observed price, the applicable MAP threshold, the observation time, and the relevant policy provision, with the supporting evidence attached.
Keep MAP enforcement separate from intellectual-property complaints. Amazon and Walmart both publish guidance stating they do not enforce MAP agreements through IP-infringement channels, and that a MAP violation is not, by itself, IP infringement. Target and Best Buy do not appear to publish an equivalent public statement, so route MAP issues on those channels through your standard seller-notification process rather than an IP claim, and confirm current policy language directly with each platform’s marketplace seller terms before escalating.
This is operational guidance, not legal advice. Have qualified counsel review your policy and escalation procedures before you rely on it. Screenshots support factual review — they do not automatically create enforcement rights or guarantee a marketplace takedown. This review step — confirming the seller, the price, and the policy line all actually line up — is where a notice is won or lost before it ever reaches the seller.
