I've come across this great website for earning vouchers – Maximiles. You earn points through a variety of methods – watching videos, completing surveys, updating your profile, signing up for offers and more. I joined yesterday and already have 600 points – 3,000 points works out as a £10 supermarket gift voucher, so it looks like I'll be cashing out soon!
My biggest earner has been the videos – you play a video (in the background or you can watch it) then vote, click onto the next video and you can earn 20 points.
You can also put your points towards a variety of items such as a popcorn maker, DS games, pack of sky lanterns and much more!
You can join using the link above, or if you'd like me to refer you then just leave your e-mail address in the comments. You'll get an extra 100 points for being referred by me.
