And that's the weird part- I have no idea how it's calculating the overseas numbers.
Keep in mind the Cart software is standalone- Asecurecart runs that end, all my "store" does is tell their cart software which product you're ordering, how much it costs, and how much it weighs. That's it.
Their cart is then supposed to simply take that generated weight and the buyer's address, and look it up on the Post Offices' own server-provided rate tables.
As I said, the software isn't "smart" enough to use things like Flat Rate boxes (unless I tell it to ship everything in FR boxes) so it should just say, okay, 2 pounds, Priority, going to Norway, here's the cost in shipping.
Except the Cart-generated numbers (for overseas shipping anyway, in-US prices are spot-on) aren't even what comes up when I check them myself on USPS.com directly.
At the moment, I've had two completed orders (Sweden and Norway) that I've been able to ship already (both book sets) and I refunded the difference from actual shipping. It's the best I can do at the moment- I have multiple requests in to their technical help line, but I don't know how fast those get responded to.
