I answer surveys sent to me via email from www.yougov.com (or is it co.uk?). They pay you 50p per survey or enter you into a draw (which is annoying - I want the 50p). I've been doing this for about 18 months and have built up a credit of £38. They don't pay you until you have £50 credit. It's not quick money but they will pay you eventually!
