I have a question regarding what I see on swappa. I'm looking for some phones for my twin daughters and stumbled upon a seller with a good track record selling "New (Resale) condition for $284" iPhone 5s. Now Apple sells them brand new for 450. What am I missing, i.e., why is he selling them at 284. Does this smell too fishy? I'll be posting a question or two to him, regarding the price but I wanted members here to chime in. I'm only now trying to figure out how much I should expect to pay for a 5s or a 5c for my kids.
