Choose PayPal option. I have sold several gadgets and PayPal payments were instant while their company check took 3 days to arrive. Everything else was good though.
I got a box and a shipping label in the mail two days after submitting the quote. I let it sit there for a week or so before finally getting to it. But four days after I shipped it back I received my money. Quite quick assuming that I procrastinated with shipping.
Sent in my iPhone for Cash after buying a new one, and the company was great! Super fast shipping, payment came within hours of it arriving at the company. Offer was reasonable for age and condition of phone. Overall five stars and would definately go back and sell again
