Hold on starman, there is a problem with buying from those guys if you want to buy a cheap handset with higher line rental and have an idea you will change down the tariff later in your contract - you cannot, according to their terms and conditions.

Buying a mobile from those guys means you are stuck with whatever tariff you signed up with for as long as your contract lasts. I signed up for a higher monthly rental to get a cheaper contract knowing that on Mobile Phones Direct I can freely change tariff by one step per month after month 9 on Vodafone.

Also, no offence intended, but why would someone use your referral link when we can go direct via the cashback sites to get money for us not someone else?
