Does SellerAmp work for Walmart?

Does SellerAmp work for Walmart? Not SellerAmp's main tool. SellerAmp SAS is built for Amazon sellers: its site lists seven marketplaces (the US, UK, Canada, France, Germany, Spain and Italy) and doesn't mention Walmart. For Walmart Marketplace, SellerAmp makes a separate product called WAMP, a Chrome extension at wamp.com that it launched in beta in September 2025. So if you want "SellerAmp for Walmart", WAMP is the SellerAmp product to look at.

Margenos makes this page, so weigh that — we've tried to be fair and link every competitor. Margenos is a Walmart reseller tool (Chrome extension and Android app) that shows whether a product is worth selling on Walmart Marketplace: fees, profit, ROI, sales estimates, every competing seller with stock, the Buy Box winner and the product's price and Buy Box history. Below we explain what SellerAmp SAS and WAMP each do, using what SellerAmp publishes on its own sites, and when each one makes sense.

SellerAmp SAS: an Amazon sourcing tool

SellerAmp SAS is a sourcing tool for Amazon sellers. According to selleramp.com, it runs in three places that stay in sync: a Chrome extension that works "while on Amazon or any website", a mobile app with barcode scanning, text search and share-to-app, and a web app. Its pricing page lists plans from $19.95 a month, each with a 14-day free trial.

Everything SAS calculates is for selling on Amazon: Amazon fees, Amazon offers, Amazon fulfilment options such as local, EFN and PAN-EU. Because the extension runs on other websites too, Amazon sellers use it for online arbitrage, including buying on Walmart.com to resell on Amazon. That's useful, but it answers "will this sell on Amazon?", not "will this sell on Walmart Marketplace?". Walmart's referral fees, WFS fees, sellers and Buy Box are different, so Amazon numbers don't carry over. See Walmart vs Amazon for how the two marketplaces differ.

WAMP: SellerAmp's separate Walmart tool

WAMP is SellerAmp for Walmart. Its homepage says it's "A product by SellerAmp" and "Built on the trusted SellerAmp platform", and the footer credits Seller Amp LLC. Here's what wamp.com and its Chrome Web Store listing say, as of November 2026:

• What it is: the store listing calls WAMP (BETA) "A sellers arbitrage tool for Walmart marketplaces", with a profit calculator that factors in selling costs and a competitor view showing who else sells a product.
• Price: the WAMP Beta plan is listed at $0 a month and labeled "Free for life!", with a profit calculator, charts and basic sales trends. WAMP Pro, with advanced analytics, is marked "Coming Soon".
• Platform: the site describes a Chrome extension and Google Sheets integration. It doesn't mention a phone app or barcode scanning for WAMP, so check their site if you need in-store scanning.
• Who it's for: the site pitches WAMP to Walmart sellers and tells people who aren't sellers yet to become a Walmart seller first.

WAMP's site doesn't say whether you need a paid SAS subscription to use WAMP. Since the beta plan is listed at $0, it appears to be priced separately, but check their site before you sign up.

The WAMP Chrome extension: how to get it

The WAMP Chrome extension is listed on the Chrome Web Store as "WAMP (BETA)", published by selleramp.com. Install it, sign in, and open a Walmart.com product page to see its panel. If you're comparing it with other Walmart extensions, open the same few products in each and check whether the fees, seller list and sales figures match what you see on the listing. Our Walmart Chrome extension page explains what the Margenos extension shows on the same pages.

SellerAmp SAS vs WAMP vs Margenos

SellerAmp and WAMP details come from selleramp.com, wamp.com and the Chrome Web Store, November 2026. Features and prices change; check their sites for the latest. SellerAmp and WAMP are trademarks of their owners, and Margenos is not affiliated with them or with Walmart.

When to use which

• You sell on Amazon: use SellerAmp SAS or another Amazon tool. It's built for that job, with a phone scanner, a Chrome extension and a web app. Margenos doesn't cover Amazon at all.
• You buy on Walmart.com to resell on Amazon: SAS again. You're judging the Amazon side of the deal.
• You sell on Walmart, source online, and want to start at no cost: WAMP's $0 beta plan is a reasonable place to start, especially if you already have a seller account and use Google Sheets.
• You sell on Walmart and source in stores: you'll want a phone barcode scanner. Margenos has one on Android, on the same account as its Chrome extension. See the Walmart scanner app.
• You're waiting on Walmart seller approval: Margenos works without a seller account, so you can research while you wait.
• You sell on both: many sellers run an Amazon tool and a Walmart tool side by side, because the data and fees differ.

What any Walmart tool needs to get right

Whichever tool you choose, Walmart research is harder than Amazon research in one way: Walmart.com has no public sales rank and no public price history. A Walmart tool has to build demand and history from other signals, so ask how it does that.

• Fees: the referral fee for the category plus WFS fees by weight, not a flat guess. See Walmart seller fees.
• Sales estimates: where the number comes from, and whether the tool admits when there isn't enough data. See the Walmart sales estimator.
• Buy Box: who wins it and whether Walmart itself is on the listing. See how the Walmart Buy Box works.
• History: whether today's price is normal. Margenos's history comes from its own daily price and stock snapshots; see Walmart product history.

Where Margenos fits

Margenos is built only for Walmart. Open any Walmart.com product with the Chrome extension, or scan a barcode in the store with the Android app, and you see Walmart referral and WFS fees, profit, ROI, max buy cost and breakeven, a sales estimate labeled with its source, every competing seller with stock, total stock across sellers, the Buy Box winner, and price and Buy Box history charts. You can track products and get push alerts when prices move, sellers sell out, or sellers or Walmart join or leave. It shows raw numbers rather than verdicts, so you decide. For a full side-by-side, see Margenos vs WAMP and best Walmart seller tools; plans are on the pricing page.
