eBay Sold History & Profit Calculator: Find Deals, Check Comps, Calculate Real Profit Sorting extensions for eBay used to work—until they stopped. Now, finding items that actually sell, checking what they sold for, and calculating net profit after fees all happen on the page you're already viewing. This extension brings sorting, deal-finding, sold comps, shipping estimates, and an editable fee calculator into one focused toolkit. 🎯 FLIP FINDER (Find deals on search pages) • Green "Deal" badge: Buy It Now listings at least 25% under recent sold median with $10+ estimated profit (US) / £8+ (UK) • Blue "Bid up to $X" on auctions and teal "Offer up to $X" on Best Offer listings: the highest bid or offer that still leaves target profit • Flags only listings that name the same model as your search; skips accessories, empty boxes, replacement parts, lots, and parts listings • Automatically cleaned comps: condition matched, lots/bundles/for-parts removed, outliers removed • Free plan reveals 2 badges per page (any type); Pro reveals all • Estimates only—verify before buying; outbound shipping not included 🔍 SORT BY SOLD (What actually sells) • Auto-sorts every eBay search by sold count & popularity—top sellers rise the moment results load • One click restores eBay's original order anytime • Works instantly—no reset, no ads, no redirects 💰 SOLD COMPS PANEL (Know your pricing) • Median sold price, price range, items sold in last 30 days • Condition filter: New / Used / Refurbished / Open box / Parts (free tier) • Pulls from eBay's own public sold & completed listings (read-only) • Appears on any product page or search result—one click away • The net profit calculator is built into the panel, so comps and take-home sit side by side for a buy-or-pass call 📊 NET PROFIT CALCULATOR (The math eBay hides) • Enter your cost & shipping cost • Deducts published eBay fees: category rates, per-order fees, promoted listings, and international fees • Shows your actual take-home—not just gross profit • Free & unlimited on every plan • US shipping estimator: USPS Ground Advantage rates by weight and zone (estimate; eBay label prices may differ) • Pro adds ROI, break-even buy price, and a maximum buy price for your target profit margin 📋 SOURCING LOG (Save items while you research) • Click any deal badge or listing to save it with comps median, estimated profit, and max buy price • Mark each item as watching, bought, or passed—track your research without a spreadsheet • Free tier stores 5 items; Pro stores unlimited and exports to CSV • Data stays on your device PLUS: Price-range stats, CSV export, and advanced sourcing targets (Pro only) 🎁 FREE 7-DAY PRO TRIAL • Activates automatically on install—no payment details needed • Existing users get it once on update • Try unlimited comps, all Flip Finder badges, sourcing log, and advanced features with no risk 🔒 YOUR EBAY ACTIVITY STAYS YOURS • Zero ads, redirects, analytics, or tracking • Search, pricing, and profit analysis runs locally on your computer • Permissions: ebay.com, ebay.co.uk, local storage — plus a license-status check to our own service for Pro.

A: The extension reads public listing pages—no account access or automation. It doesn't modify listings, automate bids, or change account settings. Q: Why use this instead of switching between eBay pages and a spreadsheet? A: It keeps sold-count sorting, deal badges, comparable prices, a sourcing log, a search report, and an editable profit calculator together while you browse eBay on desktop. Q: Will this break when eBay redesigns? A: eBay page changes can affect any browser extension. We monitor feedback, test parser changes, and publish compatibility updates when needed. Q: Do you store my searches or pricing data? A: The extension temporarily stores its comps cache and latest report in browser storage so the tools work. This page-derived data isn't sent to us, and we don't run a server that logs your searches or pricing data. Your sourcing log stays on your device. The optional Pro license check sends only a license identifier to our own service for Pro subscribers. Q: What is the 7-day free Pro trial? A: When you install the extension, Pro features unlock automatically for 7 days—no payment details needed. When it expires, you drop back to the free tier. You can also manually activate a Pro key or upgrade before the trial ends. Q: Are the Flip Finder estimates guaranteed? A: No. They're based on recent sold comps, published fee rates, and your estimated shipping. Verify each listing before buying by checking the actual listing, comps, and your exact shipping cost. Market conditions and new fees can change estimates. Questions, feedback, or found a bug? Email dadiyuhuang88@gmail.com. Works on eBay.com and eBay.co.uk.
