You will probably need to ship that by Fedex Freight, which is the next door over. Fedex Freight, Express, and "Home" are actually three different companies with different terminals, rates and rules. Make sure they understand the size, because it's cheaper to get it right than to have it rebilled later. If you and the recipient are near a Greyhound terminal, check with them. They have a service for bulky items that utilizes spare space on their intercity busses, but there's no home delivery.
