[Request] Add ability to choose how many items we want to purchase

It works just fine in every other mmo with an auction house/marketplace.
Nobody who only needs 1 apple wants to pay for an entire apple trees worth of them. It's such an avoidable issue and has been done hundreds of times before.

Not to mention the fact that an actual transaction between players needs to benefit both sides, not just sway towards the dealer/seller getting the best deal. If the transaction FORCES the buyer to pay for and receive more than they actually want then it's not a fair deal.
