I'm not justifying the price, but to give some insight in case some want to attend Comic Con for obtaining these Lego exclusives. I believe Lego is representative of many other exclusives and panels that SDCC offers. Despite the long line and wait, i would do it again for the chance to get one.
The not so glamorous Lego line at Comic Con a few hundred people behind the beginning of the line. The line then stretches over a quarter mile out the convention center northwest. Hall H is much worse.
FYI. Vixen is likely going to go cheap on eBay soon. I see little interest based on line waiting for this figure today based on reports from people in line. Prepare for people flipping it for whatever.
