I'm going to side with "UpstateNYUPSer" on this one. I know for a FACT that FedEx sales will quote rates that are at least 10% lower than UPS rates -
I went back to re-read. Taking it very literally, it states Fedex will go in and offer 10% off from UPS published rates. I can tell you any customer that ships semi-regularly will get a discount. So if Fedex went in with 10% of UPS rates (which also means 10% of Fedex rates since the published rates are the same, there is once source of equality between the two), you can sleep tidy at night knowing UPS is going in with a discount as well. Either can be lower then the others bid, it's very competitive. If UPS wants to tell their drivers to make them feel better that they only lose business to Fedex because Fedex gave a much better price, I can tell you that is fantasy-land (and it works both ways). Either can lose business for a wide variety of reasons.
Heck Fedex doesn't get some business because they aren't union, where they get other business from companies that won't work with union companies if they can help it. Wide, varying reasons.
