smart shopping carts on wordpress

Are there any shopping carts on wordpress that can do what this site does when it comes to automatic pricing mark downs?

Based on certain criteria being met the price you pay goes down. For example if you have a credit card on file you pay less, if you allow things ot be shipped together you pay less, etc. Can market press or woo commerce do this? If not, can you consider this functionality for a futture version of marketpress. They call it a smart cart.
