Here is a problem I am battling with:
Currently I sell an ebook, and give a 2nd one free as a bonus. I use the E-junkie Shopping Cart and have got an array script that adds both books with one mouse click.
This means that PDF stamping is implemented on BOTH ebooks. Which is great.
But now I plan to use Clickbank to process payments and I believe that I can't use the Shopping Cart and must instead use Buy Now buttons.
So ... how do I do this while still giving away the free bonus ebook and getting BOTH ebooks to have PDF stamping on them?
