I know what you're thinking...those companies are all scams, right? Well, I was turned onto a company by another mommy blogger (I can't remember who it was) who said she used Dollar Surveys and actually did get paid!! So, I checked it out - she was right!
Now before you get all excited and quit your day job, you can't make a living doing these surveys, but you can make a little extra spending cash....which comes in handy when you're getting extra coupons online from eBay or another site. And the best part is, once you've completed a survey, you get a notification that you completed it, and you'll be paid within a week via paypal.
Check out Dollar Surveys for yourself by clicking on the button in the sidebar. All you need is a paypal account, which is free. You just login using your paypal email address - that's all you give them so that they can send your payment. You can even sign up to get daily reminders to go do a survey, or two, or ten!! :)
