Frequently asked questions

Contact support
Can I research flea market finds without a barcode?

Yes. Use a clear photo or search by name. Add visible model numbers or maker's marks to narrow the matches. Similar-looking items can have different values, so check the details before buying.

Are sold prices guaranteed resale values?

No. Compare the actual product, condition, shipping, and listing details. An undisclosed accepted Best Offer is not a verified sale price.

Are shipping costs included in the prices?

Each listing shows its item price and any supplied shipping separately. Averages include supplied shipping costs; missing shipping is not assumed free, and Delivery location helps calculate Current shipping quotes.
