I was just wondering if anyone has had any experience with cross selling modules.

This is my first zen-cart based site (first e-commerce site actually - It's going live this Saturday)

I want to be able to put 2 products together and offer them for sale with a discount.

Which module is the best for implementing this?

Better together looks like it has the most features.... but has to be hard coded..
(I can do that but I built the site and don't really want to be tied to weekly changes, someone else is at the controls for day to day).

Or Cross Sell? But it doesn't mention in the brief outline if a discount can be applied. Can a two for one be offered?

What does cross sell allow me to do with the product other than show another product on the product details page?
Can they be combined on checkout for dollars off? Percentage off?

Any comments would be appreciated.

Thanks,
