With the recent introduction of 1.8 and the new overhauled Auction House it has come to my attention that this new in-game Auction will be used quite a lot more frequently than the Web Auction, this is great, HOWEVER, it's come to my attention there's no option to 'bulk sell' anything per say, causing the Auction to get flooded by one type of block.
My suggestion, if possible, is to introduce some form of bulk option, be it a seperate window that you can open from the Auction page, or something which let's you sell multiple stacks of the same item in one go.
For example: I want to sell 20 stacks of the Cobble, but I don't want to flood the Auction with 20 separate slots, and would rather sell them all at one given moment.
There would be an option to post them all as one offer, and when you buy it, you could receive it the same was as a gift in a chest that you place, or something?
This one offer would fill up one slot, would list the buyer, the AMOUNT of the item, the PRICE of the item, and possibly a warning to let any potential buyer know that it's a bulk sale.
Just a thought. Appreciations for your time reading and possibly considering this, and apologies for bad wording, it's late!
