You currently have the ability to add fees to an order AFTER the order has been placed. While this is better than nothing, having to charge a customer for something after they've placed orders is less than ideal. To be given the ability to add custom fees based on price, quantity, store, and especially SKU would solve several issues. If nothing else, PLEASE give us the ability to create pricing rules or discounts based on SKUs. We have customers that are charged pick and pack fees per SKU, and there is currently NO way to do that before an order is placed.
