EDIT: Well this is now dead. If you missed it, don't worry, so did I.
This free Smashbox Photo Finish Foundation Primer is a Facebook offer that was pre-announced, so (A) the signup page will probably be overwhelmed, (B) it'll probably go fast and (C) you have my permission to smash all the boxes you want if you get frustrated.
The offer was supposed to go live at 3pm EST. They're obviously running a bit late, but I've got places to go (no I don't) and people to see (yeah right) so good luck.
