For kicks, I posted an ad on Craigslist to sell my Plus 64GB Space Gray when it comes on Friday. I have never done it before and I probably will not, but some guy just offered me $1200....I mean what?! I can wait a couple of weeks for another if it makes sense So, if I upgraded my phone for $399...and sell for $1200 then I would have to buy an another one with $800 left. I assume this would be full price not sure if that is breaking even or what. Has anyone done this before? Tips, advice or should I just forget it and enjoy my new phone.
