Valued Opinions

For every survey that you complete, your Valued Opinions account will be credited with a small cash amount. When your account balance reaches £10, you can get yourself a voucher for a high street retailer. These include Boots, Argos and other like retailers. You also have the option to donate it to charity. As with many of the online survey sites offer now.
The only down side with this site is that some Surveys can be very lengthy.
