I'm using the regular Paypal shopping cart, NOT a 3rd party option like Zen cart. I want to know if I can access the items in a cart with code. Specifically, I need to prevent a customer from buying product B unless they also are buying at least 1 product A. I dont know the best way to do this, but I was thinking of somehow accessing their shopping cart via code, and making sure they have a product A in there... However I havnt been able to find a way to access the shopping cart BEFORE checkout. Any help at all is appreciated!
