I received ALL 4 boxes of these Glucerna cereals for FREE! I took 2 $10 off Glucerna coupons (valid on 2 boxes of cereal or various Glucerna items) and used them at Walgreens. As they have a GREAT register rewards deal. I did have to do 2 separate transactions, as the register beeped since the coupon states one coupon per transaction, but I did get a register rewards for $2.50 each time for a total of $5.00!! PLUS I can send the receipt into the Caregivers Marketplace and receive $1 back for each box!! AWESOME!!
