giving away free products
My client has decided that they want the featured and popular pods to have their printed catalogues in them, and they want to give them away free of charge... they will also be posted free of charge.
If I add these free catalogues to the products table, and a customer wants to receive the catalogues only, they add them to the cart, this will mean I have a cart that has a zero value; will the cart still try to connect to the payment gateway to take payment, or will the cart recognise that there are free goods in it and bypass the gateway?
