Aw man, I never win anything. It's times like this that make me think I should enter competitions and stuff.
Loquax is the site you should use. Most competitions are just enter your details and with auto complete on you can can loads quickly. Even ones with questions are just a quick google away. Tie breaker ones I stay away from.
In this country there are something like 170,000 prizes per day won in competitions which is over 60 million per year. That statistic was over 10 years ago and is probably a lot more now. Assuming a vast proportion of people don't enter competitions, some people will be winning far more than their share.
I used to enter competitions via that site every day but don't have the time nowadays.
However, when I was, I was winning two to three things a month including the following.
A mill wheel garden fountain.
Loads of skateboarding clothing
A years supply of nappies

Dvds, books, cds, computer games etc.
And the best was a 40" sony Bravia tv. That was one week after I had bought a new tv so I sold the Sony since I could get more money as it was brand new in its box. I think I got £900 for it from memory.
I have a friend who's wife is a competition addict but she enters the better ones where you have to come up with a tie breaker etc.
She is forever winning stuff. Last year alone she won an full set of AEG kitchen appliances, a caravan, a car, two holidays and lots of other small prizes.
