Add free product for customers

As a bonus I would like to offer a free product for a customer who purchases items over $100.
Is there a way that zc reconizes the cart is over $100 and give the option to choose the free gift?

Thanks in advance.

I think this is close to what I need, but I really don't understand how to implement it. Where does that code go?

Ideally I would like to have several free products available, and allow the customer to select one if they have purchased more than $x. Can this be done?

Hi
Have you find a way to do it?
Im interesting too

look up "dangling carrot" in downloads, this might do what you want, but it does modify key files
