Greyhound is the most affordable, but it does have some issues of which I became familiar with, the hard way. I had a pair of fenders sent here (Seattle area) from Ozark, MO. Things I discovered were: 1. the insurance limit on Greyhound is $300. 2. the tracking is very poor, if at all and you are pretty much at their mercy. and 3. with larger packages, they ship on a per space basis. In other words, if they stop in HoleintheWall, UT and need the space for suit cases, they will pull your fenders. Then they are 'supposed' to place them back on the next bus through. However, in my case, it took exactly 30 days for my fenders to make the trip and the Greyhound agent said he has no idea where they were or why it took so long. The box looked like it became a coffee table somewhere in the Midwest. When I sold two rear doors for a '36 panel truck to a fellow in OH, he went ahead and paid $200 (compared to $75) to ship it FedEx and put better insurance and tracking on it. Best of luck to you.
