ParodontaxWhitening Toothpaste, 3.4 oz. Per Tube (6 Pack)

I prefer Peridontax to most other toothpaste because it works. I pay @ 6.95 for it in the store, but figured it would be less expensive if I bought a 6 pack through Amazon. Turns out I was charged $11 + per tube. I sent the whole package back.
