If you have a BlizzCon ticket or a Virtual Ticket you should now be able to access the BlizzCon store and buy up everything you want in it.
Just head on over to the Blizzard Store, log in, and if you have purchased a BlizzCon ticket or Virtual Ticket with your account you will see a link to the BlizzCon Sale. One of the things though that is sadly missing is the BlizzCon shirt that I typically buy every year. However, those that missed the San Diego Comic Con earlier this year will be very please to find the popular Transforming Zergling/Baneling Plush and the Epic Purple Lanyard. Other interesting items include a new Murloc plushie (Lil’ Murk-Eye), WoW Family Car Decals, and some WCS merchandise such as a t-shirt and mousepad to get signed by your favorite pro players at the event.
I took some screenshots of the products below on what you’re missing out on if you haven’t bought your Virtual Ticket yet
