Right! Another great example. The marketeers call it a suggested upsell, such as you see at amazon where it says, customers who bought this product also bought the following products... item 1,2 and 3. With the add to cart on each product there is a no-brainer impulse experience for the customer.

In my case, our products come in different flavors, hence the radio-button attributes as part of the add to cart snippet that get embedded in the SEO'd webfomercial pages.
