How can we set-it up so a customer can purchase a physical item (prepared food or physical food item) and also provide a donation in one transaction. When both are chosen (an item and a donation), the cart says "The items in your cart have different available fulfillment methods (shipping, pickup, delivery, digital delivery). You must purchase these items separately." We'd like for our customers to be able to do this in one single transaction. Is there a way to make this work? Do we have to skirt around it and make the donation a physical item as well to trick the system? Thank you!
