Buying Dirt 3 for cheap

Ok so I was wanting to buy Dirt 3 off steam but it was $49.99. So I went to ebay looking for it. I found out that AMD was giving away coupons whenever someone bought something made by them. People were selling these coupons on Ebay for a little of nothing. I bought one for myself for $6 and I bought 2 more for $8 and $9 for my friends. I ended up spending less than half for 3 copies of the game This just goes to show that you can always find it cheaper somewhere else. :D
