01 · Scan

Point. Scan. Done.

Scan a barcode in the aisle with the phone app, or open any Walmart.com listing with the Chrome extension.

See if it actually sells.

A year of price and stock history with monthly sales estimates. Every estimate shows its source, or says when there isn't enough data.

Who you're up against.

Every seller, their price and stock, WFS or self-fulfilled, and who usually wins the buy box.

05 · Alerts

It keeps watching.

Track a product and get a push alert when the price moves, it sells out, or a new seller shows up.

Know before you buy.

Profit, demand, competition and alerts for any Walmart product, on your phone and in Chrome.

What you get

Every signal that moves your margin.

The questions that decide a buy — what it costs to sell, who you're up against, and whether it actually moves — answered in one view.

Instant product lookup

Scan a barcode, search by name or open a listing. Product, price and profit resolve in seconds.

True profit, not a guess

Walmart referral fees, WFS fulfillment and storage, your cost and prep — profit, ROI, breakeven and the most you should pay.

Sales estimates you can check

Built from Walmart's own "sold" badges and stock movement, or from comparable products when Walmart shows nothing.

Every competing seller

Price, stock, and WFS or seller-fulfilled for each offer we can see — tap a seller to open their storefront.

Buy-box history

See who most often holds the lowest in-stock price — the usual buy-box winner — plus price, offer and stock charts reaching back up to a year.

Chrome extension

The same analysis in a panel beside any Walmart listing, plus a Variations section — every size, pack count or color on the listing with its price and stock, one click to open it. Variations are Chrome-only. It reads only the pages you open and never clicks or buys anything.

Alerts

Price moves, stock-outs, and sellers — or Walmart itself — joining or leaving the products you track.

Slow-seller warnings

A clear warning when a product looks slow to sell, so your capital doesn't sit still.

Export anywhere

Send your scans to CSV or straight into Google Sheets — as many sheets as you like, on every plan.

Numbers you can trust

Estimates built on real signals.

A single sales number with no source is how a "profitable" buy becomes a garage full of stock. Margenos builds estimates from Walmart's own sales badges and stock movement — and when there's nothing to base one on, we tell you instead of guessing.

  • Measured beats modelled: Walmart's own sales badges and stock movement come first.
  • Category figures are labelled as the category — never passed off as the product.
  • Unknown shipping weight? We ask for it instead of assuming.

FAQ

Questions, answered.

Who is Margenos for?

Anyone building a business on Walmart Marketplace — from first-time resellers to high-volume sellers and teams. If you buy products to resell, Margenos shows you where the profit is before you spend.

Where do the sales estimates come from?

From the strongest signals first: Walmart's own "sold" badges on the listing, stock changes we've observed over time, and how comparable products sell. When there's nothing reliable to base one on, Margenos says "not enough data" rather than guessing.

How accurate are the fees?

Referral fees follow Walmart's published category rates, and WFS fulfillment and storage are calculated from the product's shipping weight. If the weight isn't known, we ask you for it rather than guessing.

Does the Chrome extension do anything on its own?

No. It reads only the Walmart pages you open yourself. It never clicks, browses, or adds anything to a cart.

Why do I only see variations in Chrome?

Variations come from the Walmart page itself. The extension reads the listing you have open in your own browser, so it can show them. The phone app can't read that page reliably, so variations are in the Chrome extension only.

Is Margenos an alternative to WAMP?

Yes. Margenos covers the same Walmart sourcing job — profit, fees, sellers, stock, buy box and history — in a Chrome extension and an Android app on Google Play (iPhone coming soon), on the same account, with sales estimates built from real Walmart signals. See how they compare.

How many devices can I use?

As many as you like. Your scans are one monthly allowance, shared between the phone app and the Chrome extension.

How does the free trial work?

Every plan starts with 14 days free. You'll add a card to start; nothing is charged until the trial ends, and you can cancel any time before then from your account.

Can I change or cancel my plan?

Yes, anytime, from Manage subscription in the app or the extension. Yearly plans save 20% over paying monthly.
