We're having some issues with USPS and international shipping. On a package that weighs 34 lbs being shipped to the UK from Pennsylvania, US, USPS.com says the cost is $132.00. However, the site charged only $87. Another shipment (to the UK as well) had a similar problem. USPS estimated between $175-200, but the site only charged $116.
Now, we are currently using the modification that will be part of 1.9.0 when it is released to have more control over what shipping methods are available with USPS. However, I think there is something wrong with the international shipments. It calculates shipments to Canada just fine. Just seems to have issues with overseas (like the UK).
Any ideas?
