Which? magazine maintains its independence by not accepting advertising, and the organisation receives no government funding. The Consumers' Association is the largest consumer organisation in the UK, with over 573,000 subscribers to its magazine.Until 2006, the association used prize draws similar to those of Reader's Digest to attract subscribers, but following criticism they were discontinued. The Association now attracts subscribers to its publications with free mini-guides and trial offers.
