I buy all my phones used & off contract out of pocket.
I got a great deal; It's an iPhone 6, 64GB, Space Gray & factory unlocked for $500. I'll sit back & watch everyone else go coo-coo for coco puffs over the iPhone 6s & patiently wait for the iPhone 7 next year.
To be honest I'm not terribly excited for these "s" models myself but at the same time I'm strictly interested in catching that diamond in the rough deal. They usually appear when people are desperate to update to the latest iThing & wanna get rid of their current iThing lmao.
Works out well for everyone. You get an out of contract phone for a decent price, and people like me sell them too you for that amount when we use our upgrade(s) to get the newest truest for $299 (in the case of the 64GB) with $200 to spare
