Is it possible to add shipping costs to the cart in the same way as you would with a product (i.e. a query string param).
I'm bypassing a lot of the default foxy 'add to cart' screens and building up my own cart which I pass to FoxyCart as one big form called 'checkout' on my cart summary screen. This give me a little more control over things like up-sell, analytics etc
I'd like to add shipping as one of the options on my own cart summary page, but want to make sure that appears in the foxy cart checkout page too.
I could set Foxy to free shipping and add it as a product from my own cart but that seems a bit pants.
