Have you seen people posting about this deal where they say to use the $2/1 Clairol product coupon from the 10/31 PG on Herbal Essence products? Well, tried it today and the coupon beeps. It may be technically correct that the coupon should work, but the reality is that it does not. To make matters harder to argue in the store (not that I would....I pick my battles), the only pictures on the coupon are for the hair color boxes.
If you get a cashier that overrides....lucky day for you!
