How it works

Step 1

Install & pin — 10 seconds

Add it to Chrome in one click, then pin it. No account, no sign-up, no setup screen to get through.

Step 2

Shop exactly as you do now

On any product page worldwide, open the popup and tap Compare this page. Automatic widget on Amazon, eBay, Currys, Argos, John Lewis, AO, Very, Boots, ASOS and Apple.

Step 3

See cheaper prices, right on the page

WEM checks the same item across the retailers it covers and shows a small panel beside the buy box — with a savings banner only when something is genuinely cheaper.

Step 4

Buy where it’s best

Click through to the cheaper retailer, or open the full comparison on WEM. Outbound links are affiliate-tracked and clearly disclosed — the price you pay is unchanged. Stack Coupert (or similar) for codes if you want.

No catch

  • One-click compare on any shop worldwide; automatic on Amazon, eBay and major retailers.
  • Free. No account, no sign-up, no personal data required to use it.
  • Only speaks up when there’s a real saving — no constant pop-ups.
  • Affiliate links are disclosed, and your price stays the same.
