I keep seeing Qmee knocking about on these threads. Must investigate.
Give Qmee a go. It can be a bit boring with lots of surveys on shopping habits but it certainly adds up fast. So far this month I have made £38.31 and I would expect to make around £50.00 by the end of the month if not more.
If you are into surveys give Curious Cat a go as well. Similar type of thing to Qmee and pay out is quick and easy too.
