In this case, I probably would choose Swappa to sell my 9.7-inch iPad Pro. It’s promising the highest return on my gadget, suggesting I could make back more than $550 on a tablet I paid $699 for. That’s pretty incredible, and it’s nearly twice what Gazelle would pay.

The payout would be quicker if I went with a site like Gazelle or Amazon, however, since I would just accept the price and mail my gadget in. I wouldn’t have to sit around and wait for a buyer, or worry that a sale might fall through.

The payouts for the current generation iPad Pro will drop considerably once Apple reveals the new models. If you think you might want one of Apple’s new models, try selling your iPad now.
