I tried to sell an iPAD on Swappa. It was in excellent condition, kept in a case, with a tempered screen protector and sold with all accessories. They would not allow me to post it. The said there might be a chip on it. I sent them at least 12 photos and responded to every request they had. They stopped responding altogether and didn't post the iPAD. Huge waste of time to use that site plus they ask to link to your PayPal account. AVOID IT.
