You may have read my Online Money Makers post. But I just found a new list where Hotcouponworld compiled 19 survey sites that are: legit, pay out, have little or no spam, and are a good way to earn extra money. There are several listed that I didn't know about, so I'm definitely going to check them out. I'd love to hear any feedback you guys have of the companies that they have listed!
P.S. If you are new to taking surveys start a brand new email that you give just for them, to keep everything in one place, and in case you sign up for someone who spams.
