I got an e-mail offer from the company and I thought in case someone is interested (especially if you can share it with someone). It says buy 3 and get one free plus free shipping.
The way I figured it when you buy 3 at $37.95 each + 1 free that comes down to $28.46 per bottle.
The last time I bought 12 and shared it with a CZ member and we ended up paying $30.
The coupon code number is 0606free4thoxy and it is good till July 9.
