For its Pals Rewards members only, Petco offers a Purina wet dog food or wet cat food item (up to a $1.99 value) for free via this printable coupon. (Not a member? Click here to sign up for free.) That's the first such coupon we've seen from Petco for this wet food. (For further comparison, we saw a printable coupon for a Purina Pro Plan 13-oz. Dog Food Can for free almost a year ago.)
