You joined the MySurveys site thru an offer on FC. That's a good survey site.
The points you earn on MySurveys, however, stay with MySurveys and you need to achieve a minimum number of points to cash out there. (1000 = $10; there is currently a 150 point service charge for cash)
One of nice things about MySurveys is that you receive a modest (5 pts) amount for every survey you attempt and occasionally the survey will morph into a survey that is worth more points.
I've been with MyPoints since April 2008, and have cashed out 3 times for a total of $170. The last time I waited until I reached $100 so the $1.50 service charge (150 pts) wouldn't be such a large percentage of the total cash amt withdrawn. Gift cards cost 1100 points per $10.
The service charge is a recent change; my first two cashouts were not subject to a service charge.
If you haven't read MySurveys Terms of Service, please do so. That should tell you more about cash out requirements as well as other things you need to know.
