So, I got to the bottom of it after I got hit with the extra charge for the second time. If you ship something with FedEx in a shipping tube or any other cylindrical package they charge you extra $13 for special handling. They say it is in their end user agreement. The website calculator does not take this into consideration even though it would be very easy for them to implement something like that. Just a check or radio button that you click if your package is cylindrical. You click that and bam, it adds $13 to your estimate, would help me. Alternatively, a person behind the counter could tell me. In any case, there is nothing they can do and it is my responsibility as a customer to read the shipment agreement. So ended up paying $31.50 and $31.96 for domestic ground shipment of 2 knives last month, both packages were around a pound each. On the bright side both knives arrived safe. Will pay another $13, soon as I sent one more knife in a tube, $39 worth of education......
