Simplest option for scrolling parallax shopping cart page with 10 items

Hope this question is an easy answer.
I love the way the parallax effect looks and feel it will work great to showcase my product and have some neat depth.

I also need to use rapid cart or a similar shopping cart. The rest of the site will be filled in with these items and maybe a couple more:

Rapid maps 3
Postoffice (email sub. database)
Final word

With these stacks would my best bet be buying foundation +parallax background then ad in the above items?

I will worry about how to put it all together when that time comes. Just making sure I have a solution that will fit together and makes sense.

If there is any way of accomplishing the exact same feat Minus foundation due to the steep price tag please advise*
