Most of the games I get from GF are in rough shape, but they all work, so I give them credit for pretty good quality control. It's been almost a year of buying and renting (2 at a time) from them without a lemon, which I have to admit was a bit of a surprise.
Anyway, I got a $5 coupon, plus my 5% off, which will almost negate the sales tax. I don't think I can pass this up, even with such bad reviews. $15 shipped is pretty good.
