Zantac has a new rebate offer which will allow you to get a free box of Zantac (up to $20!). To get your purchase for free, you need to make your purchase between May 3rd and May 12th, 2015. Then, go here, click on the ‘try Zantac free’ banner and fill out the rebate form.
The rebate is good for any purchase up to $20.00, which is enough to get pretty much any of their products for free. Your rebate form must be postmarked by June 15th, 2015.
