Click here to sign up for a coupon for store brand baby formula. I have done this in the past and received coupons for both Target and Walgreens valued at $3 each!
Tip: after you receive your coupon, have your friends and family sign up for it, too! Milk-based infant formula is usually priced between $11-13, so the final price is pretty low after the coupon.
Thanks to Baby GoodBuys reader Jessica for the tip!
