I am in the middle of a trade with someone in San Diego, I live in Indiana. We both sent our boxes out yesterday, and the weights were within 1 pound of each other (the box I sent was 14lbs, his was 15). We both used FedEx ground and sent to business addresses, however, he messaged me today saying that it cost him $45 to ship the box, and it only cost me $15. Why the huge discrepancy in shipping cost? Does FedEx charge more to people who are shipping from more expensive areas of the company because everything else costs more. That's my only thought. Could there just be a mistake on FedEx's part?
