[ic] Changing item price based on cart contents

[Ellen S. Ferguson]

I'm trying to change an item's price based on the contents of the cart.

For example, ITEM1 costs $5.00
If you purchase 8 items of any kind in any combination, ITEM1 cost is $2.00.

This will change on the fly based on what is in the cart.

Any thoughts would be greatly appreciated.
