Do you save and enter your Kellogg's Rewards codes? If not I highly encourage you to start doing it right away. I've gotten some really great perks just from being a member. Kellogg's has sent me tons of coupons in my member emails as well as surprise bonus codes and even things like a free $20 Shutterfly coupon code. You can find codes in all of the Kellogg's products you already purchase so why not start rewarding yourself for those purchases.
Here's some bonus codes that were added yesterday to get you started if you're new, or build up your points bank if you're already enrolled.
TWITTERIFICBONUS (25 points)
TERRIFICTUESDAYS (25 points)
HAPPYBIRTHDAYKFR (20 points)
