I'm wanting to offer a specific product for free if it's in the cart. It might be possible to do this with Buy Now buttons and bundled products but integration of that in current website doesn't work in the way that we want. So, it looks to me that customisation of the cart template include is the best way of doing this. However, I'm new to FoxyCart and cannot give this the time that it needs. Can anyone help or point me to documentation with a specific example like this? I've checked the FC docs but cannot see a close example. Many thanks.
