Vocalpoint is another great website to join. They give away free products as a way to gather information and reviews. This morning I submitted for a free full size bottle of Pantene! There is also a $1 off coupon for Starkist Tuna Creations available to print, which could make this tuna free during a great sale at your supermarket. Check their website frequently to share feedback, read articles, and to snag free products and great coupons!
UPDATE: I originally posted this exactly one month ago and I received my FREE full bottle of Pantene shampoo last night!! I was very excited to see this sitting outside my front door when I got home. Right now, as a Vocalpoint member, you can also sign up for a free sample of Puff Plus to-go pack HERE.
