Hi guys. I'm not sure how familiar you are with the website YouGov... basically you can complete surveys for money and to be enteres in prize draws. The surveys are normally conducted on behalf of newspapers and companies looking to publish information.
Theres normally a couple of each every few weeks and they don't take too long to do.

Anyway!... I did once around a month ago about next years UK general election. I'm not sure if they really do pick at random because I inserted quite a lot of extra info in the text box to give them an insight into my opinions and intentions - whilst completing the survey. They were giving away one cheque of £1000, 4 cheques of £250 and 10 cheques of £50 to random participants.
I won £50!
I can draw it out at the end of this month... although to be honest I'll probably be forced to add it into a certain female's Christmas present budget!

Just goes to show some people really do win these things!
