Right Guard offers its Right Guard Men's 4-oz. Xtreme Precision Dry Spray Antiperspirant for $0 when you purchase at a participating pharmacy retail store and redeem this mail-in rebate. (Pre-rebate prices start around $6; you'll need to select the rebate that corresponds to your store of purchase and maximum rebate values vary.) That's about $5 to $7 less than you could normally expect to pay in local stores. Participating drug stores are Walgreens, CVS, Rite Aid, and Wakefern/ShopRite. Rebate ends June 15.
