I'm thinking of trading in my iPad 2 White 32GB towards the iPad 4th Gen. I checked the trade in value and BB says it's worth $160 in good condition. My iPad 2 works great, has all the accessories and a few pit marks along the bezel from the case I used, not very noticeable. The screen has no scratches as I used a screen protector from day 1. Also, I don't have the box and I bought it as a refurb from Apple and since it's past 16 months I can't print the receipt. Will BB accept the trade without a receipt? Do I need to have the box in order for BB to consider it in good condition?
