In these days, every little bit you can do helps, especially if you are living on one income like we are. It can be time consuming, but if you can squeeze it in, completing surveys is one way to supplement your income. Each survey company is looking for different people so you never know when you will qualify for a survey, but if you have the time to devote to it, it can be helpful (in the past year Dave has made well over $500 – some in target/amazon gift cards, some in checks – but it is going towards a new tablet/laptop computer which will be nice since ours is on its last leg!).
One company we have found to be a reliable one is Global Test Market. You may want to check them out.
