I could not have had a better experience with Glyde. I sold an old iPhone, iPad Mini and Nexus 7. There was next to nothing for me to do. Answer a few basic questions for each item, step through the wizard. List them. Wait for them to be sold.
Once sold, it's just as easy. A nice package arrives, you add your item, slap on your pre-printed, pre-paid mailing label and drop it in the USPS mail. About a week later, you have your money.
