QuickSoldCheck

Auto-detect product model numbers on any page and check eBay sold listings instantly — see if it sells and for how much.

Find out whether an item sells on eBay — and for how much — in seconds, right where you are sourcing it. Hover over a product image on any sourcing site and a "Sold price" button appears. Press it and the eBay sold listings for that item — plus the median price — show up in your browser side panel. No switching tabs, no re-typing searches into eBay. It is not limited to watches. Cameras, lenses, audio gear — any product with a model number. Use it to check the going rate on used items, decide what to buy for resale, or research what a collectible is worth. ── Made for moments like ── ● You found something at a thrift store or flea market and want to know its eBay price ● You want to confirm an item actually sells before you buy it ● A sourcing site shows a wall of product photos and you want to check just one of them ● You want a quick read on what your existing inventory is worth right now ── Free features ── ● Hover a product image, press "Sold price" [10/day] 　The button appears on product images on any sourcing site. One press searches that item. ● Right-click an image or link to search [10/day] 　For when the hover button does not appear, or you cannot reload the page. ● Search from selected text [10/day] 　Select text on any page and a search button appears. Auto-search on selection is optional. ● Keyword search 　Type a model number into the side panel. This one has no daily limit. ● Median sold price 　Shown at the top of the results.

Privacy policy: https://dartmass.github.io/quicksoldcheck-site/privacy-policy.html ── Changelog ── v3.0.0 Added a "Sold price" button that appears when you hover a product image, plus search from the right-click menu on images and links. The side panel was reworked: category, date range, filters and settings now fold into a single toolbar, and the median sold price sits right above the results. Text is larger throughout. v2.3.0 Added two Pro filters. Narrow sold listings by item condition (9 conditions including New, Used and For parts) and by seller location — include only certain countries, or exclude them, with multiple countries allowed either way. Each result now also shows the seller's location. v2.2.1 Updated pricing (¥1,490/month, ¥14,900/year). Existing subscriptions keep the price they signed up at. v2.2.0 Added a route to manage or cancel your Pro subscription — while Pro is active, the "✨ Pro" badge in the header opens cancellation and payment changes (Polar customer portal). Fixed a bug where the license check was not applied correctly, so free plan limits now work as intended. Added periodic license re-validation; Pro is never revoked because you were offline or hit a network error. v2.1.4 Added a fee mode toggle (% or fixed yen) and a shipping slider to the profit/ROI calculator. Improved selection search so it no longer picks up prices and other stray numbers. v2.1.3 Added collapsible search controls and an English UI. v2.1.2 Horizontal scrolling for categories, capped at 10. v2.1.1 Added customizable category buttons (Pro). v2.1.0 Search eBay sold listings just by selecting text (10/day free, unlimited on Pro). v2.0.1 Added onboarding (first-run tutorial).
