Ok; its a good piece of writing - however.
You have to sign up with their offers, and then get 5 of your friends to sign up for a free iPod; hence making them each pay for the offers and making them each have to get 5 new people to pay for the offers and get 5 people to sign up also. Then those people will have to finalise by getting 5 people; these five people will then have to sign up and get five more people. By this point; with 625 people signed up, the first person will get their iPod - that is why it works.
You have to get five people signed up; for them to be signed up they need five people signed up, for those five to get signed up they need five poeple, for those people to get five people they each need five people. When it stops and the first person gets the iPod; it doesn't say.
Don't bring yourself into a waiting spree - where the offers being monthly will be reset and you'll have to pay for however many months of it the chain takes to complete.
Buy a bloody iPod - it'll take a day if you go and buy it, two weeks tops if you get it from Amazon - you'll get a warrenty and everything and you won't have to pay more than its worth.
Good day
