The Walmart arbitrage app for resellers

Buy low, sell on Walmart Marketplace, and know the margin first. Margenos is a Walmart arbitrage scanner for retail runs and an online arbitrage tool for your desk, with the same fee math in both.

Walmart retail arbitrage

Scan clearance and sale items in any store with your phone. See the Walmart price, fees and your profit before it goes in the cart.

Walmart online arbitrage

Use the Margenos Chrome extension on Walmart listings to check profit, sales estimates and sellers without leaving the page.

Walmart wholesale

Type a UPC and your case cost to see profit and ROI per unit, so you can compare suppliers before you order.

A Walmart arbitrage scanner that does the math

Arbitrage only works if the spread survives the fees. Margenos applies Walmart referral fees by category and WFS fulfillment fees by weight, then shows your profit, ROI, break-even price and the most you can pay.

  • Max buy cost for your target ROI
  • Every competing seller and their price
  • Sales estimates built from real Walmart signals
  • Scan history you can filter to profitable finds

On a sourcing run

  1. Scan the barcode on the shelf.
  2. Type the store price as your cost.
  3. Read the verdict: profit, ROI and how fast it sells.
  4. Buy or pass, and your scan is saved either way.
