NO, these referalls schemes do actually work, I recently received a free 60gb photo ipod worth £280 from freebiefreebie.com, I was pretty sceptical before, but I saw a video on
www.ipods43.co.uk that convinced me to join, its a video made for BBC newsnight. The newsnight team took on one of these offers and got a free ipod. It works, check out
www.ipods43.co.uk for proof, they also explain how and why they work on this site too.
