For the life of me I cannot get USPS to calculate rates. I just keep getting this:
“This shipping method is currently unavailable. If you would like to ship using this shipping method, please contact us.”
We have a USPS account, and I entered my username. As far as I can see I have set it up right?
Do you need a special API url? Or do I just use the default Magento one?
FedEx and UPS worked fine straight out of the box.
Anyone shed some light on this?
