I am attending Fan Expo this year (my third time at this convention), but the prices are pretty high, in my opinion. I am mainly attending for Jason Momoa, Tom Felton, Bonnie Wright, and the Phelp twins. Here are the prices:

Jason Momoa: $60 (Autograph), $65 (Photo)
Tom Felton: $60 (Autograph), $70 (Photo)
Bonnie Wright: $50 (Autograph), $65 (Photo)
Phelp twins: $90 (Autograph for both), $90 (Photo with both)

I remember paying $40 a few years ago at Fan Expo for Tom Felton, but now these prices have skyrocketed. I am a huge Harry Potter fan, and I love Game of Thrones. Do others find these prices reasonable, or are the prices for photos/autographs cheaper at other conventions for these same celebrities? I'd like to know before I purchase so I can compare and then decide to attend a different convention.
