The new Man-co store that Valve has added to Team Fortress 2 allows you to buy weapons and hats and other nonsense that was previously only available with time. These items are still obtainable in the exact same way, however you can now buy them at prices that range from 50 cents to 5 dollars. The first exclusive bit of items to be released for micro-transaction is a set of new weapons that were made by the community. A portion of the money is also going to those community members as well. Valve later plans to allow the community to sell things on the store too.
