or at least it didn't used to be. I'm not sure how many shipping agencies they have now, but back when I used them, they had two, so it'd take a while for the game to get back to you after you mailed one in. However, I think I recall reading something about how the postal service will now scan the games so Gamefly knows when you've mailed one in and can get your next game out sooner. Could be wrong, but for $17 a month or whatever, it's worth looking into.
