It's US$89 for just membership fee as griffin would have mentioned it before. It's expensive for international members but I guess there's a price to pay.
However, I'm prepared for it as I'm going to use it to get the Botcon 2008 box set. I've also used it to buy the discounted Astrotrain and Airazor at just US$99 for both.
So I think that have saved me quite a sum of money from not being a member of. In a way, it would also benefit fans in melbourne in shipping any TFCC figures over here in the state. I believe STL would be joining soon so it's still an advantage.
