I think I need to "use the Quantity Discount for the Attribute itself," as Ajah put it above.
I'm wanting a quantity discount when any 12 products in a category are purchased (and a different discount when any 24 products in the category are purchased, and a still deeper discount on 36 ...).
I assigned an attribute "Bulk" to all products in the category, and, using "Attributes Qty Price Discount" through the Attributes Controller, I assigned
Code:
11:2.32,23:1.75,35:1.58,47:1.47,99:1.37,249:1.22,499:1.06,999:.97,1999:.90,2999:.75,4999:.70,1000000:.65
to specify different prices for different quantities.
The problem is, this only gives the $1.75/product discount when 12 of a single product are ordered, not when 8 of one product in the category and 4 of another in the category are ordered. But that still totals 12 products with the attribute; so I thought it should give the discount. I must be doing something wrong.
I'm assuming "Attributes Qty Price Discount" is supposed to apply price discounts based on any products satisfying the attribute, not just single products.

For Attributes, these can use either the discount ratio by a Special or Sale or using the Quantity Discount for the Attribute itself ...
Attributes Qty Price Discount:
1:100,10:90,20:80,30:70,40:60,50:50
What can I do?
I'm using ZenCart 1.3.7.
I've worked many hours on this, and finally decided to post because I figure that what I want to do is so basic I must just not be getting how to do it; but it certainly must be simple to do.
Thanks for any help!
