In addition to grabbing Danger Girl/GI Joe #1 for $.99, you can grab the original Danger Girl series and the Revolver miniseries for $8.99 and $3.99, respectively. That's a lot of Danger Girl for under $15. You can find all the issues on sale here.
As an added bonus, here's the intro from a really bad PlayStation game based on Danger Girl from 2000. Enjoy!
