Purchasing multiple items in stacks.

The current process for purchasing items that come in stacks, such as an Orb of Augmentation, is ridiculous. To buy more than one you have to click and drag the item to your inventory then close the trade window and open it back up in order for another of that item type to even be made available. Not only that, you can't move a stack-able item from the trader inventory to an existing stack in your own inventory, meaning you have to keep stacking them manually as you buy them. If you are trying to trade a stack of one type of orbs to get another, this process becomes painfully tedious.

The obvious solution is to allow shift-clicking of stack-able items in a traders inventory to either:
a.) automatically move 1 of the item to your inventory with each click, to a stack if available, while NOT removing the item from the trader inventory.
b.) open a slider just like the one you would normally use to unstack items in order to select the desired amount of items to purchase.

Agreed. Also right click to buy would be nice.

So, so, so in favour of this.

Certain things should be common sense to have as a feature. This is one of them.

+1 to that
also, please make transmutation- and alteration orbs available at all magic vendors.
its kinda tedious to have to travel back to the shore encampment every time you want to exchange some town-scrolls for trans-orbs

+1 changing scrolls of wisdom for portals and then portals for orbs of transmutation is a pain in the a**.

+1, also maybe add an instant transfer from inventory to stash and vice versa.
Since here shift would conflict with changing stack size, use strg + click?

Don't like clicking 100 times to convert your scrolls to orbs? If there was an auction house, you could just buy the orbs on the market with a couple clicks, and let the free market sort things out.

As annoying as this is, I'm sure hardly anyone will care anymore after the auction house is added. Which is why I think it should be behind the auction house in priority.

Some items just need to instand refill and a right click to buy function (D2 style).

100% Totally agree it is very stiff and rigid as it is now to buy the simple items such as portal scrolls etc.
