My employer uses UPS for its shipping. I for one am underwhelmed. Fed X is so much better -- more user friendy for one thing.
We use UPS only as a last resort. They have become slow in delivery, high theft rate from packages, damaged merchandise, and unwilling to pay out insurance. The once magnificent company has really hit the skids.
Our retail store's experience with FedEx is to nearly always be shorted on packages, which is rarely the case with UPS.
