This is strange. According to Paul and Colin over at Planet Ars Linux, this is for real. The title link describes how to do this and I've followed through on it (using the eBay option, just waiting for it to get "counted"). Get your own iPod mini and help me get one of my own would you? Click here and signup.
Even if you don't go through all the way, you count as one of the 5 referrals I need to get the iPod Mini . Thanks!
Update: Ok, I was wrong. Referrers have to "complete an offer". Bah, ah well.
