Let's get you started with rewards. First of all, webcertificates are really a form of prepaid Mastercards. Go to www.webcertificate.com and check out the site. Many of us at the rewards board like to redeem for webcerts because they can be used anywhere that accepts mastercard as payment.
www.mypoints.com and www.blink.com offer webcertificates. They are very easy programs to do. I'm going to bump the "How to" post which will tell you what programs are available and gives instructions on how to do each of them. If you get stuck, just post a question and someone here will know the answer.
