Where is this module? I don't see it in my module creation page. Just hikashop cart, currency switcher, content, and wishlist.
But regardless, what would be better is if it was integrated into the flexible checkout flow. Similar to how many sites ask you if you would like a certain other product at a special price, when you go to the checkout page - like Godaddy for example.
Magento is very flexible for these. Have a look at this page:
