I am a shipping manager for a small company. We use UPS and FedEx. Let me tell you something, they are ripping folks off! I was going to order a plane from GSP but I backed out when they would not tell me the shipping charge. They know what they are doing! By the way; we charge only 10% on top of the shipping charge. Depending where we are shipping an item; neighboring state or clear across the country I try to save the customer money. If they want it the next day, I check my shipping map and decide if it needs to go ground or next day. Just today, the customer wanted his item shipped 3-Day Select (UPS 3 day service). I ckecked my map and I saved him $23.00 by shipping it ground. He would have gotten it just as fast.
