This week Pert Plus is on sale for $3.49. In the Walgreens' booklet, that you can pick up as you enter the store, there is a coupon for $2.50 off of Pert Plus. In today's newspaper (10/19) there is another coupon for $2 off of Pert Plus. There is also an internet coupon for $1 off. You can stack the Walgreens' coupon ($2.50) with either the manufacturer coupon ($2) or the internet coupon ($1) to get Pert Plus either for free or $1 overage. I tried it both ways and it worked. You only need to cut out one Walgreens' coupon as it will apply to at least two shampoos (see my last post).
