Hard choice, but I went with Price.
I'm willing to wait a while to get what I want at a good price.
I always buy my used games from EB. Using the "PPLAY15" code, the number from my EB Edge card, and the "SAVER" code, I save 25% off used games (I ALWAYS buy in bulk, so the savings really add up), and don't have to pay shipping. I get the stuff I want in 5 days (sometimes 4). You want free shipping on new games? Buy a used game with it, and use the "SAVER" code.
