Same product, two platforms, two prices. Type in a keyword and see matched listings side by side, the gap in dollars and percent, and whether the spread is worth a closer look.
Matched listings · gap in $ and % · platform medians
Pairs are matched by shared title words, which is approximate. Pack sizes, bundles, and conditions can differ, so open both listings and verify by eye before you buy a single unit.
A price on one platform tells you nothing. The spread between platforms tells you everything: where demand pays more, where a listing is underpriced, and where an arbitrage window is sitting open in plain sight.
Checking that by hand means running the same search twice, opening twenty tabs, and eyeballing which listings are actually the same product. Most people quit after three comparisons and guess the rest.
This tool runs both searches for you, matches the listings that look like the same item, and puts the gap in dollars and percent next to each pair. You get a verdict, not a wall of tabs.
We pull live search results for your keyword from Walmart first, then Amazon. Up to 15 Walmart listings and a full first page from Amazon.
Titles are compared word by word. When two listings share 3 or more meaningful words, they pair up as a likely same-product match.
Every matched pair shows the gap in dollars and percent, ranked by size, with the median price on each platform for context.
Every run pulls live search results from both platforms at the moment you click. Popular keywords are cached for up to 7 days, so a repeat search may show the same snapshot until the cache refreshes.
Each run triggers two paid live-data pulls, one per platform, and that costs us real money. The daily cap is what keeps the tool free for everyone. It resets at midnight UTC.
It is approximate on purpose. Listings pair up when their titles share 3 or more meaningful words, which catches most same-product matches but can also pair a 2-pack with a single, or a renewed unit with a new one. Treat every pair as a lead, open both listings, and verify by eye before you buy inventory.
