Been doing this crossword for years and never won a thing, there's never any winners names published and for a long time been suspicious that many prize crosswords are just means to gather names and addresses for junk mail and telemarketing when phone numbers are requested.
I also doubt that postal entries are even opened.
Yesterday's crossword announced that postla entries will cease come 30th March...so they get even more revenue from text submissions.
In my opinion...if prize crosswords are genuine then prizes should go up as the money they make from text entires must be substantial.
