I buy games from wherever has a sale, nowadays. Like, I bought Tron 2.0 and KOTOR for $20 each at Best Buy.
Console games, I usually buy from the local Gamestop or Walmart. And I have no problem buying used console games, if they're a good deal, and they have a manual and the original box.
Actually, if it's a big title, I prefer to buy it brand new.
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.
