I LOVE being a member of the Kashi community. Not only do they send samples quite frequently, but they send GOOD coupons. Just recently they sent me a sample of their cereal bars, a coupon for a free box, and five more $2 coupons... just because I signed up on their website. They have sent me free cereal coupons, free cookie coupons and others. Plus every time, they have sent me dollar off coupons along with them.
