1) Nope! It's a store in llyod center, which means it is always open to the public, but the super secret signal is a previous year con badge (2009 or earlier, since 2010 hasn't happened yet) and that gets you a discount on your total purchase at the store! Huzzah!
2) This is.... still up for debate... I imagine they can't actually stop you.... but we are still checking with the venue (Llyod Center) on this... if you do cosplay and we haven't recieved confirmation they are okay with it, just please try to be courteous and chill whilst at the mall. Obey ALL rules and regulations and be nice to the fine suits and badges... it's their job to keep everyone safe, including you!
