I was at Wizard's Chicago comic con this past weekend and Dean Cain was supposed to be there.
I didn't bother to try and see him because I don't do that autograph bit. Especially not at the premium prices that they charge. I don't know the specifics that existed for Dean's signing but generally you have to have a convention admission and a special ticket/admission for each celebrity you wish to see. The prices generally allow you to talk with the celebrity for a few moments while you get an autograph, or for a higher price you can get the autograph and take a picture with the celebrity.
Prices depend on the heat factor of the guest, Those on current hit shows or movies tend to cost more than those who haven't been around for a while.
Dean was probably there to hype his new psuedo reality competition show.
Tank (who might have gone against his normal tendency if it had been Terri rather than Dean)
