ok I have been going to the offers pages and was wondering after you sign up for info should you get credited for that or is it mandatory to buy something each time to get credits? As many of the offers say no purchase required. I get to a congratulations page and it offers to complete more great offers and its one offer after another and tons of emails from the ones I did sign up for but only a couple of credits? Is this typical? What is a normal earning from the offers if done daily?
