The only thing that sells out faster than San Diego Comic-Con tickets are BlizzCon tickets. You'll have two days this month to try and snag tickets, with the first set of going on sale April 24 at 7PM Pacific, and the other on April 27 at 10AM Pacific. Tickets will cost $175, and you'll want to be F5ing the official BlizzCon website to try and get your pass.
There will be 200 tickets going on sale for a pre-BlizzCon dinner as well, set to take place on November 7 with proceeds going to the Children's Hospital of Orange County. These tickets will run $500 and go on sale on May 1 at 7PM.
BlizzCon takes place November 8 - 9 at the Anaheim Convention Center in Los Angeles, California.
