The seller can take it to a UPS shipping store. They will box it and ship it for him. All he needs to do is drop it off. I have done this with fenders before.
Or, if there is a Greyhound station near him, they will ship it is well. They are quite reasonable. I've shipped hoods through them.
With Greyhound, he will need to cover it but nothing fancy. I used brown paper to wrap my hoods - nothing more.
