If you like Renuzit products, they are offering a free Renuzit cone to the first 30,000 people that like them on Facebook. After you like them, you will enter your email and they will send you a $1 off coupon. These are typically priced at $1 or less- so the coupon should make it free.
It looks like some people are having trouble getting the coupon to print- so they have an email at the top of the page for any questions.
It will be $0.88 at Rite Aid next week = $0.12 money-maker!
