Right now on coupons.com there is a coupon for $3/1 for Similac and $5/1 for Enfamil, since these are manufacturer's coupons they can be stacked with store coupons, like the $2 in the Rite Aid ad....
did you know you can also "stack" these with the formula check you get in the mail from the companies. These are considered a form of payment, a check, not a "coupon", so you should be able to use all three. That means you can get some pretty cheap and possibly free formula!
