Do you mean not clear on cost for a single day? Otherwise, there's a brochure here: http://www.botcon.com/BotCon2013/San...20brochure.pdf
Basically, $365 (Primus) for the entire weekend and the boxset + free attendee figure + casino night, or $175 (Protoform) without those things. Alternatively, you can partner with someone who has a Primus package and get the Minicon package. This is similar to the Protoform, but gets you into the Casino night for $90. They will probably post single day prices closer to the con.
