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 iPhone Duo 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 iPhone Duo 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 iPhone Duo worth?
Between $50 and $1,901 depending on storage, carrier and condition, as of October 28, 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.
