My Deal Verifier

Verdicts on every eBay, Mercari US, and Buyee (Japan) listing. Real market data, real math, real verdicts.

Stop guessing whether a listing is actually a deal. My Deal Verifier adds instant verdicts to every listing on eBay, Mercari US, and Buyee (Japan) — both search results and individual item pages. No more second-guessing, no more opening eBay sold comps in a separate tab, no more math on the back of a napkin. TWO MODES, TWO VERDICTS, ONE CLICK. • Buyer mode — "Am I getting this cheap?" Compares the listing price to real eBay sold comps and shows GREAT / GOOD / FAIR / HIGH / OVERPRICED with the dollar savings and discount percentage baked in. • Reseller mode — "Will I profit flipping this?" Computes landed cost, subtracts eBay fees, and shows Good Buy / Borderline / Pass with your projected ROI and net profit. EVERY SUPPORTED MARKETPLACE, EVERY VIEW. • eBay US — per-tile badges + item overlay • Mercari US — per-tile badges + item overlay • Buyee Mercari Japan — per-tile badges + item overlay • Buyee JDirectItems Auction (Yahoo Auctions) — per-tile badges + item overlay • Buyee PayPay Fleamarket — per-tile badges + item overlay DEAL WATCH — BE FIRST TO EVERY DROP. Save any eBay search and our servers monitor it 24/7. The moment a new listing posts at a great price, you get a push notification — on desktop AND mobile. Buy it before anyone else scrolls past it. • Runs in the cloud — works even when your browser is closed • Instant alerts the second eBay indexes a new listing • One tap opens the listing straight from the notification • Unlimited saved searches on the free tier 🇯🇵 BUYEE CROSS-CHECK ON EBAY. Japanese resellers buy items on Buyee and flip them on eBay at a 40–80% markup using the exact same product photos. Now when you search eBay, the extension automatically scans each tile's image against Buyee. If the same item is sitting on Buyee at a fraction of the price, we drop a ribbon on the tile showing the real landed cost — single AND consolidated shipping — with the savings dollar amount. One click opens the Buyee listing so you can buy direct. SMART JAPAN LANDED-COST MATH. For Buyee listings, the extension automatically adds forwarding, international shipping, and the current Japan DDP tariff so you see the landed cost in USD before you commit — not the yen sticker price. WORKS WHERE YOU ALREADY SHOP. No workflow changes, no extra tabs, no URL copying. Install it and start seeing verdicts the next time you land on a product page. A free account unlocks Deal Watch push alerts — everything else works anonymously. PRIVACY-FIRST. • No tracking, no telemetry, no analytics inside the extension. • Reads only listing pages on eBay, Mercari US, and Buyee.jp — nothing else. • Sends anonymous keyword-only queries to our backend to fetch public eBay sold-comp data. • Buyee cross-check sends only the eBay tile image URL and title — no personal info, no listing history. • Settings stored in chrome.storage.sync. We never see them. • Full privacy policy: https://mydealhq.com/privacy FREE FOREVER. No credit card. Part of the mydealHQ toolkit. Paid Pro tier unlocks additional features in the other three extensions (Bundle Risk Checker, Shipping Trap Checker, Bulk Supplier Opportunity Scanner) — coming soon.
