I understand what you're describing but that's based on every item type having the same price and then giving a discount off that price if the order hits the quantity.
What I'm trying to do though is a little different.
The store has 3 item category types:
There are multiple products within each of those types at varying prices. For instance:
Type1 - Cool T-shirt Design 1 - Price 14.95
Type1 - Cool T-shirt Design 2 - Price 12.95
Type2 - Beans - Price 1.99
Type2 - Bread - Price 1.79
Type3 - Paperweight - Price 5.99
Type3 - Brick - Price 3.99
I want to run a discount where if someone buys x number of Type3 items, they are 8.00 each.
So deducting a set amount (2 in your example) is not going to work.
Appreciate the input though!
