Add Additional Costs/Fees to an Order
I am developing a shopping solution in 7.1 and I would like to add additional costs when a customer requests additional services or requests expedited order processing. The additional services are based on being able to calibrate products, but it is too complicated to add as a variation. I would like to just add additional fees as a line on the order and set the price in a custom widget. Can you add an item to an order that isn't a product defined in the eCommerce module?
