I'm probably late saying this, but anyways, right now on Steam, until July the 10th, there are some really good deals on games. I haven't actually bought anything yet, but I want to get the Valve Complete Pack, which is only £24.99 (was £139.81!) and contains almost every Valve game.
Anyways, there is a whole lot more deals on, and the chance of winning the top 10 games on your Steam Game Wishlist, by gaining tickets from game / miscellaneous Steam achievements. I have no idea if this is going on in America too since I can't seem to get onto the US website to check.
