[SUGGESTION]: Quantity Select when buying stackable items.

Have you ever tried to buy something from the Market Board and find out they are only selling it in amounts a lot higher than you need? For example, let’s say you want to buy a single material to craft a single item, and when you go to the marketboard they’re selling stacks of x99, and you only need one or two! Wouldn’t it be great if could select the amount we want to buy from the stacks?
But wait! Wouldn’t that suck for the seller? Actually, it wouldn’t! I’m a main crafter and I sell about 200+ items a day. And the thing is, if the items are too expensive, it isn’t wise to sell a stack of 99 because there’s always someone else selling only 1-5 of those and the buyers would only buy what they need or the closest to what they need since they probably don’t have money enough to buy a x99 stack or they simply want to spend less money. So what does smart sellers do? They sell on very small stacks.

That’s where the trouble comes: we have to add one stack after another to the market board, and whenever we get undercutted on prices or we need to make a change we have to edit the prices one by one. Moreover, what if you selling too much stuff? This becomes troublesome.
At the moment I need all my 4 retainers in order to sell the stuff I craft/gather daily, because selling this way makes a lot of space, not only on me retainer, but also on the market board: You can easily find a single retainer selling small stacks of a single items multiple times!
So adding the option for buyers to buy the quantity they need would be a lot more profitable and beneficial to both partys (in my humble opinion).

Wait! I know what you’re thinking… if they add this option it would reduce the chances of people buying more expensive stuff due to convenience and the market would be a competence of who’s selling cheaper, the prices would drop and the economy would collapse… well, sorry to brake it to you, but we’re already at this point! This option would help the cheapest product to sell FASTER and that would increase the chances of the next in line to be sold, and we could probably sell all the stuff on only one retainer, and also this would ONLY affect the stackable items, armor/weapons and any non-stackable markets would remain the same.
This is just my humble opinion, this idea might as well be very wrong. However, as I see it, it might help a lot on the economy of the server.

It takes a little bit of time and effort but what I do is buy one of the large stacks, use what I need from it, then re-list the rest in much smaller stacks for higher price per item. They usually sell quickly and I make back the Gil I spend.

No. You don't get to pull out one can of Coke from the case just because you don't want 24. You buy what the seller is offering or you move along.
