Is there a way to buy a multiple of an item (SKU)?
For example: I have an SKU named LifePoint, and i want to buy 100 LifePoint.
(in another word N * my_item).
I found this workaround, but am looking for something better.
PS: I'am using In-app Billing Version 3 and my item is Unmanaged (to buy my product many times).
Thanks in advance!
