Commerce (and Commerce Kickstart) rendering add-to-cart buttons on any page? Can someone school me or point me to a resource where I can learn how to render the add-to-cart buttons for specific products on any page? I know how to get them in a view and I'm using Commerce Kickstart.

The goal is simple, for the slider, I'd like to include an add-to-cart button for the slideshow product in the slide itself. The slides are content but they're not controlled by a view as Commerce Kickstart has it's own module for the slideshow. Even if it were a view, I don't think it would help. 

So is there a way to print out an add-to-cart (even in PHP) like finding the add-to-cart variable for a product by id or something and just rendering it? Thanks.
Solved: Experimenting I added a product variation field to the Slideshow content type. This essentially creates a new line item type but that's okay. I can now render the field in the view and it adds to the cart like it's supposed to. Just some CSS now and it will be just fine.
