Your Favorties at Texas Ren Fest???

I can get tickets for $15 from my work.
I hear they are $21 at the door.
Is there anywhere cheaper for discount tickets?
I hear HEB and Randalls sells them.

Also its my first time there in years.
Anything I should definitely check out?
Food? Entertainment?

THANKS!

p.s. I hear they have a Halloween theme this weekend.
It will probably be my nephews greatest Halloween ever!
Im going as Jason Vorhees.
