If you’re a member of Eat Better America (a General Mills company), check your email inbox for an invitation to request your copy of a $10 coupon booklet. I believe this is limited to current site members only, and available quantities are limited.
If you’re not a member of Eat Better America, you can sign up HERE. It’s free, and your membership will allow you to print coupons for brands like FiberOne, Betty Crocker, Green Giant, and others. Signing up will also get you on the list for future special offers like this coupon booklet.
