Best Buy used to be really great about trading in phones. However, in the past six months they have become super strict about condition. They consider your screen scratched, and therefore your phone in poor condition, if you have any micro-scratches on your screen (you know, the ones that are nearly impossible not to get and you can only see when your screen is off and you tilt it just right). Unless you have had a screen protector and case on your phone from pretty much the second it came out of the box, assume Best Buy will give you the poor condition value. You're most likely to get more money from Gazelle.
