Discount on combination of items

Hey, guys. It's my first post, so hopefully you guys can help a n00b out :blink:. I was wondering if it's possible to create a discount such that if a user buys a certain combination of items, a discount is given. For example, if I have Item A and Item B, the discount is only given if the customer buys both Item A and Item B on the same purchase, but not just one or the other. I tried searching the forum, but I couldn't turn anything up. Any help (including links to forum posts or FAQs) would be helpful. :bigups:

Go to the downloads section (top of the page) and search for Better Together.

Thanks, swguy! I'll definitely try this out.

I'm looking for a Combo Products module for Zen cart. I mean, the swguy modules are really cool but I don't know if it works for "Downloadable products" and the Admin (commercial) it run from the Zen-cart admin?
I remember that it was a module that create Combos.. but I can't find it!

Thanks .
