I agree the subscription pricing is ridiculous. The cover price in the newsagents in the UK is (currently) £4.50. Surely if they want people to sign up to eg the commitment of a digital plus print subscription, they need to offer a better price than £18 a month?
I am sure I do too many crosswords anyway, and of all of them, the ones in the Observer are those that I would most readily give up. So unless the Observer decides to offer a hugely reduced puzzles-only subscription, I am relaxed about bowing out.
Having said all that, for those in the UK, you may want to check out getting a digital subscription through your local library. In my part of the UK, I can read the whole of today's Observer on line and for free through my library subscription - Everyman and Gemelo are on pages 124-125 of 188. It may be a challenge getting them to print out, but I think I did manage it, when I was once struggling to access the Spectator Crossword.
For those who want to make a postal submission, the address to send your Everyman solution is no longer the same as the Guardian Prize puzzle. It is instead the same as for Gemelo -ie:
Everyman No. 4,128
The Observer
22 Berners Street
London W1T 3LP
UK-residents over 18 only.
