Short of having all of your products in a single category, is there no way to charge a single flat or percentage handling rate for an order as a whole? I have my products divided into five categories (call em cats, dogs, snakes, voles, and wombats). For each category I selected as the handling fee method Flat Fee Per Shipment + % of Products in this category. What I expected this to get me was that each ORDER was charged $1 + the percent for each category. But instead each CATEGORY gets charged $1 plus a percent. Which means the guy who buys 1 each a dog and a cat gets charged more handling than the guy who buys 2 cats.
Is there a way to specify a flat or percentage handling rate that gets applies to the order as a whole, regardless of how many different product categories the customers is buying from?
