Questions
How do I find out what something is worth?
Take a photo of it and upload it above. Check This Deal identifies the item and its condition, and gives its fair market value used, its retail price new, and comparable items, each linked to what similar ones have actually sold for. It works for furniture, electronics, tools, bikes, collectibles and most other second-hand things.
How can I tell if a marketplace or classifieds listing is a good deal?
Upload a screenshot of the listing, or use the Chrome extension on your computer. You get a verdict (good deal, fair price or overpriced), how far the asking price is from the market, an offer to make with a message to send the seller, and red flags that can mean a scam.
Is it free?
Every new account gets 3 free appraisals. After that, credit packs start at 12¢ an appraisal, and reopening a listing someone already appraised costs nothing.
How accurate is the appraisal?
It is an AI estimate from Google's Gemini, not a professional valuation. Check the comparables before you buy or sell, and for antiques, jewelry or anything valuable, ask a professional appraiser.
