Page 47 in the magazine says £1 for 3 issues and £11.25 for a quarter. Not sure how that works for 13 issues a year?
Follow the subscription process on this site and on page 46 and you can get 3printed issues for £1 down and £11.25 a month.
You can cancel any time in the first 3 months so I would not worry. The new subscription company seems far more efficient than the old one.
