Hi,

I'm building a custom form that will present product according to a taxonomy term.

The customer will choose one product from the first list and one from the second.
My form will look like:

A. choose one product from the list (radio button):
- option A.1
- option A.2

B. choose one product from the list (radio button):
- option B.1
- option B.2

I can't use attributes because I want to use the separate products in other places and to benefit from them being nodes.

I want to mimic the product kit module and pass a one time product kit to the cart.
This one time product kit will have a discount and all the other features but won't be stored in the database.

When the user make the order, the separate products will be listed but not the product kit.

Another invisible product can be used to track the number of one time product kit purchased.

Does this makes sense?

Do you have ideas how to implement it?
What hooks/modules can I use?

Thanks
