I have a selection of products that come in several "variations." The problem that I run into is my pricing, I need to set it based on catagory, instead of based on product, since I discount "bulk" purchases based on total order within the catagory, instead of based on the individual.

example: Linen shirt, avail: blue, green, brown, red, white.
Pricing: 01-10shirts = 9.95ea (any combo of colors)
11-20shirts = 8.95ea
21-30shirts = 7.95ea
31+ shirts = 6.95ea

Currently I'm just "refunding" my customers after I do the calculations when the order comes in, since the ZenCart doesn't alowe me to set up these kinds of controls on the catagories.

Any suggestions or help would be awesome!
