Because buying 50 gift boxes for the duck in a box is a pain.
A lot of the alchemy recipes call for unusually large amounts of gold shop items. It'd be nice if we could buy gold shop items in bulk because it's a hassle buying them at the moment.
Agreed. Right now the only GS items I need to get in large amounts are the Pancakes, which I need 10 of to make one Cache. But I typically make at least a few Caches a day and I like to buy a lot of the components I need in bulk, so being able to buy several Pancakes at once would make things a LOT easier for me.
