I personally do a lot of shopping for used games on Amazon. You can find games in Like New condition, just make sure you buy from a reputable seller. I hate when I get a game from GameStop and it's missing the case or they put those freaking stickers on the actual cover...
Buying digital would consume space HDD for PS3.
For example, RE6 for digital would take 10GB but no sales tax; while the physical copy only take space 4GB of your HDD + sales tax.
I eventually decided to buy from GameStop, and you know what's strange about it ? There is no manual booklet on that RE6 game when I opened !
What the hell ?! I thought EA is the only game company that put online manual booklet, and now this Capcom following..
