Where to source, what to look for, and how to check every item with numbers before you buy.
Updated November 1, 2026 · By the Margenos team
How do you find products to sell on Walmart? Pick a sourcing method (retail and clearance stores, online arbitrage, or wholesale), build a shortlist of items that already sell on Walmart.com, then check each one with numbers: profit after Walmart's fees, a sales estimate, how many sellers and how much stock are on the listing, who wins the Buy Box, the price history, and whether you're allowed to sell it. Buy only what passes, and start with a small quantity.
This guide covers where to look and how to check what you find. For category ideas, see what sells best on Walmart; for the full product checklist, see how to know if a product will sell on Walmart. Margenos, a Walmart reseller tool (Chrome extension and Android app), 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. We'll point out where it helps, but every step below works by hand too.
Most Walmart resellers use one of three sourcing methods, and many mix them. Each trades effort, cash and repeatability differently.
| Method | How it works | Good for | Downsides |
|---|---|---|---|
| Retail and clearance | Buy discounted items in stores and resell them online | Starting small, learning fast | Hard to repeat; one-off finds; travel time |
| Online arbitrage | Buy discounted items from retail websites | Sourcing from home, more items checked per hour | Shipping time and cost; deals get crowded fast |
| Wholesale | Buy cases from brands or authorized distributors | Repeatable stock, cleaner paperwork | Larger orders, supplier accounts, thinner margins |
Clearance aisles at big-box stores, drugstores and home stores are where most resellers start. Scan anything discounted and compare it to the Walmart.com listing. The finds are often one-offs, but you learn quickly what sells. A phone barcode scanner turns a slow aisle walk into a fast one; see the Walmart scanner app and how to resell Walmart clearance.
Online arbitrage is the same idea from a laptop: watch retail sites for sales, coupons and cashback stacks, then check whether the item is profitable on Walmart. You can check far more products per hour, but so can everyone else. A browser extension that shows Walmart numbers on the listing saves the copy-paste. See online arbitrage for Walmart.
Wholesale means buying by the case from a brand or its authorized distributors. You get repeatable stock and invoices that prove where the goods came from, which matters if a brand or Walmart asks. Margins are usually thinner, so the numbers have to be checked carefully. See Walmart wholesale.
Sellers who already win on Walmart have done some research for you. Open a listing, look at who else sells it, and browse their storefronts for items you could source cheaper. Margenos's seller lookup shows a competing seller's products with profit for each.
Whatever the source, profitable products to sell on Walmart tend to share a few traits:
Here's one product run through the checks. The numbers are made up to show the method, not real Walmart data.
The math is the same whether you do it on paper, in our Walmart profit calculator or in a tool. More detail in how to calculate Walmart profit.
A Walmart product finder won't hand you winners, but it makes each check faster. Margenos does it on one screen: open any Walmart.com product with the Chrome extension, or scan a barcode with the Android app, and you see fees, profit, ROI, max buy cost, a sales estimate labeled with its source, every competing seller with stock counts, total stock, the Buy Box winner, and price and Buy Box history charts. Track a product and you'll get alerts when prices move, sellers sell out, or sellers or Walmart join or leave. No Walmart seller account is needed. See Walmart product research and the best Walmart reseller apps to compare options.

Pick a sourcing method (retail and clearance, online arbitrage or wholesale), shortlist items that already sell on Walmart.com, then check each for profit after fees, sales, sellers and stock, the Buy Box, price history and restrictions. Buy small quantities of what passes.
Walmart doesn't offer a public sales rank or product finder for sellers. Tools like Margenos show fees, profit, sales estimates, competing sellers and Buy Box history on any Walmart.com listing or barcode scan, which speeds up each check. Margenos makes this page.
There's no fixed list. Profitable products are new-condition items with steady demand, room for profit after fees, few sellers whose stock moves, and no low-priced Walmart offer on the listing. See our guide to what sells best on Walmart for categories.
Generally no. Walmart's resold products policy prohibits items not in new condition unless you've been invited to its Resold program.
Walmart's prohibited products policy lists pre-approval categories including books, ingestible products, topical products, fragrances, luxury brands, software and custom content. Check Seller Center before you buy.
It's your call, but many resellers look for a few dollars of profit per unit and around a 30% return on cost, so there's room if the price drops. Work out your max buy cost before you pay.
Wholesale gives repeatable stock and invoices; retail arbitrage is cheaper to start and teaches you faster. Many sellers start with retail or online arbitrage and add wholesale as they grow.
