Where can I sell an old iPhone in Yerevan ?

I’m trying to sell my old iPhone and I’m specifically looking for offline stores in Yerevan that actually buy used iPhones for a decent price.

I’m not looking for options like List.am or other online classified ads , I want an actual shop where I can walk in and sell it directly.

Does anyone know reliable stores in Yerevan that purchase used iPhones? Any recommendations or personal experiences would be super helpful!
