I want to charge $5 minimum shipping for an order, and use multiple categories. Is there a way I can have a flat minimum $5 for the order even if an order comes from three different categories? In my testing, it looks like there is a $15 shipping charge.
Can this be done? Did I do my testing wrong? I had thought that it could be done, and based my shipping scheme around this minimum $5 per shipment.
Background information: We sell only physical products, and will not be using live shipping. Most of our products can be fit into one of the USPS flat rate shipping boxes. We have a category that's $1 handling for any number of items in that category (little things like resistors and switches), figuring whether it's one item or ten that $6 would cover the shipping. We have another category for stuff that's bulkier (some safety sunglasses and motors) where we're saying $2 per item in that category for shipping, in addition to the $5. Enough of those bigger items, we'll need a bigger flat rate shipping box, and the extra money will account for that. But we only want the minimum $5 shipping for the entire order, not per category. So if someone order five resistors and three sunglasses, it should be $12 for shipping -- $1 (resistors) plus $6 ($2/ea for 3 sunglasses) plus $5 (base price).
