Alright, the details on this are still a bit vague to me, but here's what I understand so far. At 2:00 EST on Friday, October 2 through Tuesday, October 6, you can have a chance to get one of 50,000 free Herbal Essences coupons for a free 12oz. product. That means they're giving away 12,500 each day and the first giveaway starts in about 2 minutes. Go to the link above and click on the RSVP option over on the right hand side.
The rules don't say whether or not you have to also become a fan of Herbal Essences on Facebook, but it can't hurt I guess. You know what else can't hurt? Becoming a fan of HIF. However, dropping a giant box full of books on your foot most certainly can hurt. I think it was punishment for not having read half of the books.
