[box=right] There are already over ten twenty thirty one hundred and forty thousand a lot of crates for sale on the Market.[/box] Update: Valve has opened up the market to Dota 2 items. "We've opened up the beta to include items from Dota 2. The items that you can buy and sell are currently limited to tools such as Diretide essences, Greevil eggs, and keys" (Linux Steam Group). ----- Valve has launched the Steam Community Market today, a place where you can buy and sell in-game items for Steam Wallet funds. That's right: You can now sell your hats to other players for credit to buy games on Steam. For the beta period only items in Team Fortress 2 can be traded and for the moment it seems only Tools can be bought or sold. The process is very simple. To put an item up for listing just click the "sell an item" button and select something from your inventory and choose a price. To purchase just select an item from the list and all currently listed items of that type will be listed for you in order of lowest to highest price. Click buy now on whichever one you like and a little pop-up to add funds to your Steam wallet and place the order will appear. There is a Steam transaction fee of 15% with a minimum of 1c for each transaction, paid by the buyer. There is also a game-specific transaction fee (to be set by each game's publisher) which has been set as 10% for Team Fortress 2. These fees are subject to change. If you have any further questions you can check out the FAQ page here and if you want to keep track of updates to the service or join in the official discussion for it you can join the official Steam group here.
