Right Guard offers its Right Guard Men's 4-oz. Xtreme Precision Dry Spray Antiperspirant for $0 when you purchase at a participating retail store and redeem this mail-in rebate. (Pre-rebate prices start around $5; you'll need to select the rebate that corresponds to your store of purchase, and maximum rebate values vary.) That's tied with our May mention (which had fewer participating stores) and about $5 to $7 less than you could normally expect to pay at these local stores. Participating stores are Walgreens, CVS, Rite Aid, Target, and Kroger. Rebate ends September 15.
