Suave is giving away a full value coupon on their facebook page. You can go here and like them, then just fill out the quick form to get your 12.6oz. free Suave Moroccan Infusions shampoo or conditioner coupon.
The coupons will be mailed in 6-8 weeks. This is only available to the first 50,000. The site is getting heavy traffic so just keep refreshing the page if you need to. It did work for me.
