So basically lets say I wanted to be afk or whatever but at the same time I wanted to buy an item.
Example: Lets say i wanted to buy an RPG for 900k I can goto to my shop or where ever it id just pick the RPG and put a buy order for 900k
Theres not always going to be the item of choice in the auction house.It's a good idea but I don't think it will be added , it might cause the server to lag even more than it already is..
There could be a tab in the Auction house between buying & selling. Sellers would have the option to sell instantly to one of the buying offers in the buying page or put their item up for auction instead.
