I have been using these tips for a year and a half. I have saved a significant amount of money, which has helped me paid off over $25,000 in debt; I am slowly getting out of debt. I will also include a list of legit, survey/research companies that offer gift cards (such Amazon, Groupon, Starbucks, Old Navy), airlines miles, magazines, etc. I have been a member of these companies for years. I've been getting these rewards without much effort.
Good luck to you.
