That would depend on what tier your name gets drawn at. The pre-sale tickets are all $420 (+ shipping & handling), the main sale tickets will be $240- $320- $390 (so the max. will be $390, +shipping & handling). If for some unlikely reason you don't win in either of those, open sale tickets go up in March, again up to $390 + s/h (4 tickets max).
You cannot get tickets in multiple drawing or in drawings + open sale, you can only get them in one of them.
The ticket page & faq are linked in my sig, they should answer most of your questions.
