It is an exclusive club, those who get picked to be Nielson Home Scanners.   Basically if you are selected, Nielson gives you a home scanner so whenever you shop you scan the barcode of the item you buy.  This tracks spending patterns.  For doing this, you get to quickly earn gift points that are redeemable for name-brand merchandise, including electronics equipment, jewelry, household items, toys, and much more!  I hope I get accepted! Go here to apply.
