I confirm that, with Rapidcart Pro, you can only have one page with your store.
The simplest way to handle this could be to use Cart3 or Paysnap, wich are different, quite cheap, and where you can have different products on different pages with the same store/account…
And for every body who is interested in stores made with RW, I proposed to share them here (with almost no results until now, but I do think it would be a very interesting subject to share…).
