Please allow us to purchase (as long as we have room) multiple versions of non stackable items.  The biggest offender is Reblath and Militia gear but there are others.  I want to be able to buy 40 reblath helms all at once, not count in my head RMB 1 RMB 2.... RMB 40 get to the end and realize that I clicked either 1 too many or 1 too few times and have to swap back over to buy 1 more or "remember" that next time I only need to buy 39.  There is a "Buy Multiple" button let us use it for anything not just stackable items.
