I contracted for a couple months at Microsoft as a gratuity clerk giving out MS software to participants in studies. Most of the studies are here in the Seattle/Redmond area but they also do studies out in the field. I recommend to anyone <<who does not care how much info MS has on you>> to go to
MS usability studies and fill out a profile.
While I worked there, my personal best was giving out $27,000 worth of software in one day.
