Tried to do some searching and couldn't find anything, although I thought I'd seen a thread awhile ago. I saw something about instructions on sending back your trade-in, but I haven't received any instructions. The only thing in the box was the invoice. I also looked back through my emails from Samsung and didn't see anything regarding instructions for sending back the trade-in. I'm getting ready to send it in, but I want to make sure I do everything right so I hopefully get the $425. I'm trading in an iPhone 6S + that I used for a couple of months. (and is in great condition) Anyone know if I should have gotten instructions for sending it in? Thanks!
