WEM Price Compare

Instantly see if an Amazon or eBay item is cheaper at other retailers. Free price comparison, right on the product page.

See cheaper prices from 10+ retailers while you shop on Amazon and eBay — now in both the UK and the US. WEM Price Compare is a free, privacy-friendly price comparison tool that automatically finds the same or a similar product across other major retailers and shows you the best deal right on the page, so you never overpay. NEW IN 1.2.0 — GLOBAL SUPPORT • Shops in your currency: amazon.co.uk and ebay.co.uk compare in pounds; amazon.com and ebay.com compare in dollars. Savings are always like-for-like — never a £ price pretending to beat a $ price. • 90-day price history: on products WEM tracks, see the 90-day low at a glance and open the full price-history page with one click. • Compact mode: prefer quiet? Turn off auto-expand and the panel collapses to a small pill showing just your potential saving. A TRANSPARENT ALTERNATIVE TO COUPON AND CASHBACK EXTENSIONS • Free forever — no account, no sign-up. • Privacy-friendly — no personal data, no browsing-history collection, no fingerprinting. Product titles from supported product pages are sent to wem3.ai only to fetch comparison results, and anonymous usage stats (a random install ID, never your identity) help us improve. • Honest by design — the panel appears only on Amazon and eBay product pages. It never rewrites links, never injects coupon codes, and never overrides another site's checkout. One click takes you to the cheapest retailer. HOW IT WORKS 1. Open any product page on amazon.co.uk, amazon.com, ebay.co.uk or ebay.com. 2. WEM checks its product data for the same or a similar item at other retailers. 3. A small panel shows the best price found. If you're already on the best deal, it says that too. WEM may earn a commission when you buy through a link. It never changes the price you pay.
