Additional product on checkout/cart page

[bufaso]

Hi there,

I am using Joomla 3.4.8 & Virtuemart 3.0.12.

I would like to display on checkout/cart page an additional product in three different variants (like shippment) because I want this product only be sold when other products will be sold.

How can i manage this?


Thanks for any help!
