Nielsen’s Homescan Consumer Panel represents millions of Americans.  By scanning the bar codes on your purchases and completing short surveys, you make your opinions count in the marketplace.  Nielsen sends you a hand scanner (pictured) to scan your purchases and you receive gift points redeemable for electronics, household items, jewelry, toys and more.  I did this for years – Rachel claims it was just to skewer their results with my extreme deals …  tomatoes, tomahtos
