discount if 2 items appear in cart
I am trying to setup a discount if there are 2 specific different items ordered at the same of 10% and I am having trouble figuring out the proper discount code setup. I just want to discount the price of those 2 items but not any other products or the subtotal. Additionally, is there a way to setup an "add to cart" button that will add these two items at the same time from static pages. (i.e. ItemID "a" & "b") Thank you.
