I Have My Reasons
I know you mean well but please don't try to talk me out of my design goal. The purpose of putting multiple items into the cart is to get a discount on a specific bundle of products. In my case, it's FIVE products. If the customer buys Product A, B, C, D and E, they get a discount.
If they don't want all five, let's say they don't want Product B, they can remove Product B and still have A, C, D and E in their cart but no discount.
Your suggestion is all or nothing ... With using one product to represent all five, either all five are in the cart or all five are out of the cart. There's no other option. And that's not what I want.
Also, if you wrap all five into a "sixth" product that represents all of them, then it's much more difficult to track sales of the individual products. If I want to know how much of A that I sold, I have to sum up all the sales of individual A and then I have to count all the packages that it might be "hidden" in. That won't be easy.
Thanks for the tip on Blue Sky. It might help now if you guys updated that old tutorial that talks about Blue Sky Footwear. It's not a lot of fun to go searching for something that doesn't exist.
