I know some people think paid surveys are a waste of time, but I thought I'd pass this link along anyway. I've been doing paid surveys since high school, and Pinecone Research is one of the best companies I've worked for. They send a couple of paid surveys every month, and they tend to be pretty interesting. If you're interested in registering with them, you can do so by clicking here.
I've been a member for about a year, and I've made around $75. When you're doing everything you can to make and save money, every little bit helps.
