I think I know the one you're talking about. On their forum and website, you can find the prices. You also need to pay for the entrance.
If it is the event I think, you would have some photos (free) with the guests that you can pick or you can get your own items sign. There are also photoshoots for some guests if you are interested.

Hey!

I think I know which convention you mean. Like jdp3577 said, you pay your entrance fee, then you pay for each autograph you want. They will usually sign your own items if you'd like, but you do have to pay a fee per signature.

Enjoy!

yes you pay the entrance fee, then another fee to get the autograph, yes you can take your own items. they will sign as many as you want, but you'll have to pay the fee for each one. It can get expensive, but I never miss them when they come near me.

Hi
Will appreciate your advice re a signings convention. I live in Europe and there is one in the UK in July. Debating whether to go.
How does it work? You pay an entrance fee, then another fee to meet one star and get his/her autograph? Can you take your own item (s) for signing or is it restricted to one signature only?
Will really appreciate your advice
Thank you
