I don't think anyone will tell you exactly what they make. but those who are 100% involved and are very active posting deals an coupons make more than $200-300 every month, I think...just my thoughts :)
About $100 is my max. I haven't gotten a check in a few months because I broke the $600 ceiling last year and didn't want to fill out the paperwork. I should see checks again this month. It might be a doozy.
