Here's the setup I'm trying to make, but can't quite figure out.
For normal orders inside the US (I'm in the US) shipping is 3.60 flat fee, plus a dollar handling fee for every item in the order. I've got this working great. But, now international shipping has become a concern. For international shipping, I would like to be able to just use either USPS or FEDEX international shipping, and let those things handle it completely.
So, can I combine the two, use the flat fee for US orders only, and USPS or FEDEX international for everything else?
