You'll need a free Facebook account for this one, but it's worth it! The $5 off $25 coupon you get today is only the beginning, as they are planning to offer more exclusive Facebook coupons. You can post your ideas on their wall about what you'd like to see in their stores.
You can become a fan of either Toys R Us or Babies R Us. The first coupon is good online only the day you become a fan, so plan your shopping around that. Today's coupon has 2 promo codes, FBSEP26 and FBSEP521002. Some exclusions apply.
