Gamefly Sales (Mafia II, The Darkness II, NBA 2K13, Dead Island, Killing Floor, Others...)

I think both the US and UK stores are doing it, but they are different coupons.

Some more UK offers.
(Thanks to a post on Hookups.)

The prices get really good after coupon. I got Mafia II and The Darkness II for $11.98, combined, with no tax. Well, that and 5% cashback off with FatWallet (You could probably do better, check CashBackHolic for other places, that might not be as trustworthy.) and some off my card, too.

It is nice having an American store with good cashback offers, run a decent deal, for once, so I could get full cashback.

Also to note, I think you can find better deals on most of the other stuff. I just posted the best that are actually really good deals. You can search around the store and find other ones.
