I am eligible for an upgrade with Verizon. The 64GB iPhone5 is $400. I am fine with my current iPhone4 and am content with buying another one used, should my current one need replaced. A completed listing search on ebay shows the 64GB sealed in box going for a little over $1000! What am I missing? Minus some fees and such, a profit of over $500? Am I seeing this correctly? Any tips for selling? Only allow USA or open it up to international buyers. I am a somewhat established ebay seller with no feedback issues or anything like that. Any help is appreciated.
