Rarely write reviews, but excellent experience with Gazelle made me!
"I got the box fairly fast after submitting my iPhone's condition online which was also in minutes. Pre-paid shipping label was in a foam-protected box. I simply put my phone in the box, sealed it, and dropped of at the USPS store. I got my money within 1 -2 weeks or so. Just so worry-free, hassle-free. The instructions and interfaces were concise. Will use Gazelle again!"
