It is back again, earlier this summer Bayer gave away free bottles and now they are doing it again. All you have to do is go HERE and put in your email and they will update you when its live. You just go back to the site and sign up for your free bottle. I scored a free bottle earlier. And there is also a $1.50 coupon you can stack with Target mobile coupon to snag a free bottle. Good luck.
