I have been looking round at the different packages available. Seems to be £5 a month is about the norm.
Then I had a glance on the auction site and found this item 9715345272
It don't seem a bad package for a years worth of use at £10.50 as a one off payment for a whole year. I will probably find out different.
I will let you know how I get on with them. Purchased mine today
