SM surveys while they are from Greenfield they actually work differently. SM surveys are run through a third party who sets a cookie on your machine and once you get the congrats screen the cookie pings them and they award you credit. They assume that they will get credit from Greenfield the next day so they don't hold the credits back like most reward programs like SR have to do. It is a gamble for the third parties but one they are willing to take I guess.
I would definitely visit the auto credits for me thread and the other surveys to see if you can reach your cash out goal since you aren't that far away from it.
