This is one of the survey sites to which I’ve belonged for a few years.  Nielsen (national consumer panel) offers surveys and, if you are accepted into the Nielsen Home Scan program, a hand-held scanner to scan your purchases.  Once a week you transfer the info via phone and that’s it!  You earn points for each survey and weekly scan which accumulate quickly – quickly enough to get some great gift cards.  They’re legitimate, been around forever.  And extreme couponing must really blow their bell curve.  Why yes, I purchased 840 bottles of liquids this week and 300 cans of iced coffee last week.  You mean that’s not normal!?
