Thanks for the link. I noticed that they also sell a multiple upselling module. I am currently working on a client who has three software products and one has 12 modules that we need to upsell on it. Doing it the conventional way (add to cart - back - add another - back - etc.) it gets confusing for the customer. On top of that, two of the products also are available with or without support. I'm finding this cumbersome too setup. Do you think that Jon's Multiple Upselling Links for X-cart module (
