Maru Voice is amazing. They'll give you free Paypal gift cards just for taking quick & free online surveys. Takes 2 secs to sign up and you can get earning straight away. They send really regular surveys and you can redeem the points you earn for Paypal gift cards, Amazon vouchers and loads more.
Plus be in with the chance of winning £1,000 when you sign up. I know that would come in handy right now!
