Magic machine at CVS

Do you know about the magic machine at CVS? Its the red machine located inside as you come inside the store...you can scan your extracare card as many as three times a day and get coupons. My last two coupons were awesome...5.00 extra bucks for joint their new beauty program and 50 cents off a dove bar which made it a moneymaker cause they are already FREE this week! They also have christmas stuff 90% off and my store had tons.of m&m's left that rang up 39 cents for.a big bag!
