A thus far particularly laborious method of making small amounts of money online is to sign up to sites that allow you to fill in online surveys for a small cash reward.
With hundreds of 'cash for survey' sites to choose from I decided in the end to go for 'valued opinions' as by paying in voucher codes the rewards for surveys tend to be a little higher, and because the site seemed to have better reviews on 'money saving expert' than some of the others.
I have read rumours of people making as much as £200 anually in cash and vouchers by signing up with several sites at once (Christmas shopping sorted) but I am personally struggling to imagine how I am ever going to make it to my first threshold of £10 without loosing the will to live.
One extremely common annoyance to look out for is filling in half a survey to be told you don't qualify for it, so be warned about that.
This all being said, if you have a spare half an hour in the evening and you’re sent a survey to fill in; it does eventually mount up.
Eventually!
