Amateur Photographer Subscriptions: Buy NEW Don't RENEW

I took out a two-year subsciption deal (two years for the price of one) for the print version of Amateur Photographer. The renewal notice arrived a few weeks ago. The renewal was for 20% off. Thinking that was a very small discount and wondering if their marketing department was following the insurance companies and banks in penalising brand loyalty, I looked up the new subscription rates. Yes, they were penalising loyalty, was the answer, as the comparison below shows:

2 years Renewal £218.32

2 years New £163.99

1 year Renewal £116.44

1 year New £86.99

Needless to say, I bought a new suscription and threw the renewal notice into the bin. Is there no end to the rip-offs in Britain pulled off by marketing departments offering automatic and semi-automatic renewals to customers?
