I think has been discussed somewhere but i cant find it again... i know complicated attribute pricing is possible with Rules, and something about custom line items, but i wonder how to accomplish a price in the case where
- something has a size - width, height, etc. Price per inch.
- There are different materials at different prices per inch.
- the same product can add multiple items (First is 23"x34"x6" and the second 23"x34"x10")
- A fixed price is set when a second level is added. (combination fee)
