I guess 5 bucks difference really isn't a big deal right? I usually buy from ebgames.com.
saving $5 for a used game isn't worth it to me. An Gametop card can help tho, cause you save 10% on used games. That's nice.
I gave up buying game online tho, cause with the shipping, it's not worth it. Although, sometimes www.gogamer.com has some AWESOME deals.
