Limitation to purchase from npc's.


Setting the scene here:
You have a lot of inventory space.
The game has designed stacks so that you can have 1 item slot filled up with a stack of 100.
You however want to buy 40.000 stacks.
The game allows you to purchase only 100 items at a time (1 stack at a time).

Would you be ok with that?
This would result in you having to click and buy 400 stacks of 100. Which can be considered a somewhat tedious task.

Or should the game allow you to purchase an endless amount, as long as you have the inventory and cash to buy it?
So that would mean, you're able to purchase 40.000 stacks with one click.
