$400 in gamestop credit, would be less if you ask for cash I think.
Amazon will give you $500 credit for their trade-in. So unless you are hard up for cash, GameStop's offer is worse. And Amazon pays the cost of shipping.
I just sold my 64gb wifi only for $550, just saying......
When did you get this amount and what was your net in-pocket after any selling costs? Was this in the last couple days via Craigslist (no fees/costs) or a month ago via ebay?
Sold it on Monday to a friend, $550 upfront, no fees or extra cost. Not a bad deal.
