Privy — eBay Product Research for Serious Resellers Stop guessing. Start knowing. Privy is the Chrome extension built exclusively for eBay resellers who treat selling like a business. Open any eBay listing and within seconds you'll see exactly whether a product is worth buying — profit margins, real sales data, competition levels, and a clear buy or pass verdict. All without leaving the page. Know Your Exact Profit Before You Buy Most resellers guess at margins. Privy calculates them precisely. The moment you open a listing, Privy automatically pulls the sale price and shipping cost, then calculates your real net revenue after eBay's 12.9% fee and payment processing (2.9% + £0.30). Set your target margin — 10%, 20%, 30%, or 40% — and Privy tells you the maximum you should pay for the item. No spreadsheets. No mental maths. Just a clear number. Real Sold Data — Not Just Active Listings Active listings tell you what people are asking. Sold listings tell you what people are actually paying. Privy analyses recently sold items for the same product and shows you monthly sales volume, the median selling price, the typical price range, and the full min-to-max spread. You'll know in seconds whether a product moves fast or sits unsold for weeks. Understand the Competition Instantly Privy counts how many active sellers are competing for the same product and calculates a competition ratio against monthly sales. You'll see immediately whether a niche is wide open, manageable, or completely saturated — labelled clearly as LOW, MEDIUM, or HIGH. A Clear Verdict on Every Product All that data feeds into a single recommendation: GREAT OPPORTUNITY, BUY, CAUTION, or AVOID. No ambiguity. No information overload. Just a clear, data-backed signal so you can make faster, smarter sourcing decisions. Works Right on the eBay Page Privy opens as a clean side panel — no new tabs, no switching apps, no disruption to your workflow. Research a product, get your answer, move on. It works across all major eBay regions including UK, US, DE, FR, and AU, with currency automatically matched to your local site. Track Every Product You Research (Pro) Upgrade to Pro and every lookup is automatically saved to your personal dashboard. Filter by verdict, review your history, and export to CSV — so you can build a sourcing database over time rather than starting from scratch every session. Built for UK Resellers Doing Arbitrage Unlike bloated multi-marketplace tools that try to do everything, Privy is laser-focused on eBay. It's built by an eBay seller who got tired of expensive platforms that weren't built for the way resellers actually work. Privy is affordable, fast, and gives you the exact data you need — nothing you don't.
