This appears to still be available if you missed it last time!
Head over and fill out your information to request a coupon that is valid for a FREE Full Size VO5 Shampoo or Conditioner! It says sign up for a “chance” and select consumers will receive the coupon. I’m not sure what the qualification is to receive it, but I’m guessing it has something to do with the household size (maybe the more people, the better odds). This offer was posted on the VO5 Facebook page.
