I have a very good customer who told me today she is very upset with Fedex. She said that they've been shipping contracts out in fedex letters for years and have always been charged the letter rate. She said she opened the bill today and found they are now charging by weight over 8 ounces. I told her this was news to me and that I've always been under the assumption that if it fits in the letter, it goes at letter rate. She talked to customer service and they told her they are now auditing all letters. Great job Fedex, to provide more revenue, you're going to screw good longtime customers. She apologized to me and said her boss wants her to switch to UPS!
