I've made over $100, BUT it is VERY time consuming. It's very common to be "disqualified" from a survey at the very end. I do not blame swagbucks, but the survey itself. They will take 25 minutes of your time, let you finish, then disqualify you. Luckily, I screenshot EVERY survey to prove it, and swagbucks has credited me every time.
It is unfair though, seeing how much they profit off of our work.
Inboxdollars is horrifying. Swagbucks is the only one I've ever found to at least be decent.
