Colin told me that he uses a freight broker to get the best rates. The general idea is that you go pick them up at whatever freight company's warehouse / depot. The freight broker will get them close to your house based on your zip code. The guy from the freight company warehouse called me when they arrived.
Frankly, I was very pleasantly surprised at how well it all worked.
I rented a UHaul trailer (I intensely dislike UHaul, btw) and picked them up; they had a forklift to put them on the trailer for me. Take along a couple tie-downs to keep them from shifting in the trailer.
First picture is frieght company forklift on the way out of their building with the axles; second picture is the axles in the UHaul trailer.
