I do the big "M" using a print copy from my local library (Hillsboro, Oregon, USA). This is usually 11 days late and sometimes not in the paper and I am now an addict.
BTW (modest snicker) I can do it now in usually 2 days but I have the Chambers 20th-cent Dictionary and am usually reduced at the end to a search-every-word for the last clue. Without that, no hope of solving.
I get the Financial Times subscription online and get through breakfasts with that. I could subscribe to the whole Sunday Times likewise just for the crossword but it's getting expensive. The local library charges 10 cents to make a copy.
Any ideas?
