Tribe Village is open for new registrations! It's a great market research company that pays you to take free online surveys. You'll get points for each survey you take and can exchange your points for £5 Amazon vouchers once you've got enough.
You'll get 20 Tribe points just for signing up so you'll be well on your way to getting your first voucher.
I've heard great things about Tribe and it's a fantastic way to earn a bit of extra spending money throughout the year.
