Sell Brand New & Unopened Items in San Diego — Fast Cash, No Hassle
Got something brand new sitting in a box you'll never use? San Diego BuyBacks buys sealed, unopened retail merchandise — from Lego sets and Dyson vacuums to Oura Rings, Breville espresso machines, and golf clubs. If it's new-in-box and has real resale value, we want to buy it.
We buy from upgraders who bought two of the same thing, gift recipients who received something they don't need, resellers with overstock inventory, and anyone looking to convert unused items into immediate cash. No fees, no listings, no strangers. Just walk in and walk out paid.
Not sure if we'll buy it? Text us a photo at (619) 918-2526 — we reply fast, even after hours. The worst we can say is no.
