Get a great deal on Neutrogena shampoo this week at Walgreens! This morning I bought two Neutrogena Anti-Residue Shampoos and they rang up buy one get one 50% off, even though my store didn’t have the BOGO 50% off sale tags. Stack a $2.00/2 Smart Source newspaper coupon with a $2.00 Walgreens coupon from page 17 of the February Savings Book. The booklets are found in the front of the store by the weekly ads. Use one Walgreens coupon at checkout; the register will automatically apply it to each shampoo. The final price is $2.09 each!
