This is for a 4.4.2 cart.

There are products in four categories that we want to sell by the foot. The base price per foot is modified by certain specified lengths and by color. For example, picket 1 costs $0.57 per foot. It is sold in 12 foot lengths, so one picket is $6.84. If it is tan there is a 15% surcharge, so it would cost $7.87.

We want to display the price per foot on both the products list and the product detail page. Because the products have wholesale pricing based on membership we can▓t just write it in the product description, though.

I was able to display the price per foot on the product detail page (not the products list page) using price modifiers for both length and color, but then the calculations are incorrect; both the percentages are just calculated on top of the base price per foot, so that a 12 foot tan picket would only cost $6.93. Using a variant for length gets a correct calculation for total price, but then:
a. I couldn▓t get the price per foot to show, and
b. I couldn▓t add wholesale on the per foot price

To make this even more complicated, we want to have certain bundle sizes specified. If the customer buys a broken bundle, any pieces outside of the bundle should cost 10% more. This last part is less important, but in an ideal world that is our goal.

Does anyone have any ideas about how to do at least the price per foot part?
