I have set up a shopping cart and the FedEx module is working :) The client wants to continue to use FedEx for their online store as they have used that in their physical storefront for quite a while. Now, they also want to add a handling fee to every order. I am not sure how to add this. It's not an option for the customers to choose, it needs to be added after they've placed all their products in the cart (or at any time). What's the best way to do this? Thank you!
