Getting a book signed via mail?

[somedude]

I would like to get a book about a TV show signed by one of the cast members as a birthday present for a friend.
Anyone know if its possible to do this via mail?
Have any tips?

My best tip is to find out beforehand if the star even signs, that way you don't end up losing your book.

If they do, the process is the same as sending any other item, and make sure your SASE has enough postage to cover the book's return.
