I use ZEN Cart to sell digital products. I want an add-on that will give the customer an OTO (one time offer) for every digital product that he/she buys. EX: A customer buys an ebook called xyz. When the person goes to his/her cart to buy it, this person is presented with an OTO for another ebook that is similar to the xyz ebook. This ebook is less expansive than the original price if this person were to buy it seperatly because It's a OTO.
If the customer buys 2 or more ebooks, the person is presented with 2 or more OTO on the same page.
Not all ebooks will have an OTO. Just the one I choose to have an OTO will have it.
