If you add all these products to your cart, you will be able to see the discount in your cart because of Discount Preview

Overview:

This product complements my Combination Discounts extension by allowing you to have a single button that adds all the items to the cart. The button is displayed on the product info page for products which do not have attributes and which are linked using an add_linkage() statement with only PROD purchases specified.

FAQ

Q: Why doesn't Buy The Set work with products with attributes?
A: Buy The Set automatically adds the items in the discount to the cart. You can't just add something with attributes to the cart automatically because you don't know the correct attribute settings; there are as many possibilities as the arithmatic product of the number of options. There's no way to know which one is right. So then the customer would have to go in and modify that item and add a new one with the correct attributes (because you can't edit an item in the cart), and then delete the old one. In addition, if there was javascript validation of the attributes, this would be sidestepped if I allowed Buy The Set to automatically add items to the cart. So given all these complications, I decided to not allow it and clearly advertise this fact.

  I charge a fee of $30 for Buy The Set.
