In the CVS ad this week beside the herbal essence sale price of $3.49 it states “Get a free Herbal Essence up to a $4.99 value when you buy any Herbal Essence shampoo, conditioner, or styler. Which is essentially BOGO free! I had to explain my theory on the ad to the cashier 3 times but finally got approval from the manager. Pair it with the BOGO FREE coupon from the Sunday paper and get both totally free! I paid tax only on 4 shampoos and 4 conditioners!!
