I have said often that Crosswords are ephemeral and Magazine Comps are purely prize led - these quizzes are almost wholly Charity Fundraising ones and have weeks and often months to run.
Some are almost totally asked and often whilst there is still time for others to send in for a copy,hence a drop in sales
We the quizzers have the right to refuse to send for 'no asking' quizzes if we wish - I for one always try to honour the quiz setters wishes.
Now of course, someone will say - if you don't want to look, don't click on the thread.
