Chrome extension · Walmart online arbitrage

The Walmart Chrome extension for sellers

Open any product on Walmart.com and see profit, ROI, sales estimates, every competing seller and the buy box, right beside the listing.

Right beside the listing

Open any product on Walmart.com and Margenos opens next to it: product, profit calculator, offers and charts, with no copying between tabs.

Every seller and their stock

The full offer table with fulfillment (WFS or seller-fulfilled), stock with a cumulative total, and a link to each seller's storefront.

History and buy box

Buy box price, Walmart's price, offers, reviews and rating over time, plus who usually wins the buy box.

Online arbitrage on Walmart, faster

Browsing Walmart.com for products to resell is the core of online arbitrage. The Margenos Chrome extension reads the listing you have open and shows the numbers that decide a buy, including the listing's variations (sizes, pack counts and colors) with their prices.

  • Profit calculator with Walmart referral and WFS fees
  • Sales estimates with their range and source
  • Badges Walmart shows on the listing
  • Variations with price and stock, one click to open

Safe by design

The extension reads only the Walmart pages you open yourself. It never clicks, browses, or adds anything to your cart. Sign in with the same email and password as the Margenos app.

  1. Add Margenos to Chrome and sign in.
  2. Open any product on walmart.com.
  3. Type your cost and read your profit.
