Questions

Common questions

Who am I actually selling to?

To the buyer you pick, on their own site. We compare published prices and send you there — they email the prepaid label, inspect your Galaxy S21 Plus and pay you directly. We're not in the middle of the transaction, so there's no extra step and no extra cut.

What if my offer is lowered after inspection?

That's between you and the buyer, and every buyer we list will return your Galaxy S21 Plus free if you decline the revised offer. Check the price-lock window on each row above — it's how long they'll hold today's quote.

How much is the Samsung Galaxy S21 Plus worth?

Between $5 and $80 depending on storage, carrier and condition, as of October 2, 2026. Pick yours above for an exact number.

Should I sell locally instead?

If there's a buyer near you, usually yes — same-day cash and the price is confirmed in person. Sell by mail if there's no buyer nearby, you can't meet during the day, or you'd rather not meet in person.
