Joined up to the free ipods thing, where advertisers get you sign up for a trial offer and you can then refer others who sign up etc etc. If you get five others to sign up you get a free ipod - so i thought i'd have a go.....
It doesn't involve any buying, just a trial with, say a DVD rental company that you have to cancel after a few weeks. It is legit - all a desperate act on the part of advertisers, capitalised on by a company which does genuinely give away ipods if you get five others to sign up. Don't take my word for it, see what the BBC had to say http://news.bbc.co.uk/1/hi/programmes/newsnight/3683524.stm
So, if you have a mo - try it. I'm always up for getting freebies wherever possible, who isn't?
