We've updated the Steam Community Market with a new method of purchasing - Buy Orders. A buy order is an order to purchase a commodity item at or below the specified price. This order stays in place until it is fulfilled or cancelled.

Buy orders can only be used on commodity items, which are items that are all identical to each other (no variations in description or function). To start with, we only have marked Half-Life 2 Trading Cards as commodities (links below). We'll expand that as we work through any issues with the system.

You can have multiple buy orders outstanding - up to 10 times your current wallet balance. If an item gets listed for a lower price than what you have on your buy order, you will receive the lower price. The buy order with the highest price gets priority for purchasing newly listed items. If there are multiple orders with the same high price, the oldest buy order gets fulfilled first. Buy orders can be cancelled at any time, by you or the system - if the item changes, if you no longer have enough funds in your wallet, or if there are any issues during an attempted purchase.

Here are some links to Half-Life 2 Trading Cards on the market if you'd like to try out the feature (Note: all sales are final!). Please post any feedback in the market forums (http://gtm.you1.cn/groups/community_market/discussions).
