If you go here:
you will see the rebate offer and link to the form for a Barnes & Noble Gift Card. You will get $5 for spending $15 or $10 for spending $25 and you can submit up to two per household. In addition to the Barnes & Noble gift cards, you will receive a complimentary Healthy Eating Tips bookmark and coupons for all participating Hain Celestial Group brands.
The "fine print" does say, "Valid on Garden of Eatin’® snacks, WestSoy® non-dairy beverages, MaraNatha® nut butters, Health Valley® cereals and snack bars and Earth’s Best® Sesame Street®, Tots, Kidz and Frozen Foods. (Not valid on Earth’s Best jarred or other infant foods)" so you can't use it on regular Earth's Best stuff, only the products that are linked with Sesame Street.
Not a bad deal if you are already buying the products. The rebate offer is good through September 30, so you've got some time to purchase if you are interested.
