I clicked on the link in my email for the first survey, then completed two more, and so far all I have are rocks in my account, not the $10 bonus. The email says the bonus will hit the account upon completion of the third survey....I'll give them a day before sending them a request for the points.
EDITED TO ADD: After completing a few more surveys, beyond the required three, the $10 bonus posted as "Punchcard."
