Sam's Club has $4 off each of its pump bottles of Nexxus Shampoo and Conditioner (44oz each). Also if you add both to your cart, you will be just over $30 which should mean you qualify for a $10 egift card.
So basically $22 for two big bottles.
Not sure how much these are going elsewhere, but looks like a good price compared to costco, which is for two 33 oz bottles for $34 shipped plus tax
Edit - free shipping for Plus members - free pickup for everyone else
