Four Seasons are giving 2x free condoms if you fill in a quick survey. You can either keep the free condoms or donate them to those in Africa. You also get a nifty penis ruler.
Apparently the free condoms are only available to those who have bought Four Seasons condoms previously. There is supposedly a serial number inside the package.
Edit: There is also free Four Seasons screensavers for your computer http://www.fourseasonscondoms.com.au/downloads.php
YES! Battle helmets here I come!
