Badges for the 2013 Comic-Con International in San Diego will go on sale to the general public at 9 a.m. Pacific on Feb. 16. And they'll probably sell out by, what, 9:10? 9:15? There's no telling, so if you want one, plan ahead and move quickly.
Buying a badge requires a Comic-Con Member I.D., as CCI will email the registration link to folks with IDs two days before they go on sale. If you don't already have a Member I.D., you'll need to get one by Feb. 11, as the site will close to new registrations and changes on Feb. 12 and will not reopen before badge sales begin.
Also, if you purchased a four-day badge with Preview Night during pre-registration in August 2012, or if you are a professional or guest of professional who has registered for a Comic-Con 2013 professional badge, you are not eligible to participate in open online registration and can't buy a badge on the 16th.
Prices for badges are:
