We are seeing incredibly high international shipping rates when using the USPS API.
Our customer was charged $546 for “USPS First-Class Package International Service” That order was for 5 items each weighing “170” which we understand to be grams from the documentation.
We also have a 20% markup set for the service.
At first we thought that it was perhaps treating the grams as ounces, but that doesn’t work because First Class International is limited to 4lbs. When we check the rate in our own shipping solution we see somewhere around $25. Any ideas?
