If you like surveys then come and check out the LiveTribe website and you can earn points to spend on gift vouchers and other things as well as this you get to voice your opinion.

Fun survey site with multiple prize options upon completion. I love the free lotto entries and website design is innovative making the experience more enjoyable.

LiveTribe is in my top 3 survey or rewards sites.
They have high quality surveys, not too long or hard to navigate. The survey invites are really quite frequent, but you only get a small reward per survey. However, considering they are shorter surveys and there are many it's pretty easy to build up points.
You can redeem points as vouchers which I like, but you can't redeem cash.

I seem to work hard for every cent I earn. I start at 6am and finish at 9pm (I do have a few hours off in the day but still) and when I have the odd hour off I enjoy going onto rewards sites like livetribe where I can answer a few questions and earn some extra cash or a gift voucher without having to work up a sweat.
