Free eBay Tools
Every tool is free, works instantly, and needs no account. Built to fill the gaps eBay's own search leaves open.
Watch Serial Number Lookup
Decode a Rolex, Tudor, or Omega serial number to find the production year, then search eBay for matching listings.
eBay Category Finder
Type any item to get the exact eBay category, available filters, and a direct search link. 20,000+ categories.
eBay True Cost Calculator
Enter a price, shipping, and your state to see the real landed cost — item + shipping + sales tax — and how much over sticker you're paying.
eBay Hunt Builder
Combine max landed cost, local-pickup distance, condition, and buying format in one saved search — filters eBay's own saved searches can't combine.
