In celebration of the Mann Co Store's second birthday, Valve are throwing a big party in the form of a sale. Hats! 25% - 75% off!

While the sale doesn't include every single item and (if you've played enough) you probably have a lot of the items already, there are still some good savings to be had. This is the best way to clear out some loose change from your Steam wallet and procure some head-based decoration. Or guns. No, you're just going to buy hats aren't you. I know I am.
