Target has a printable coupon HERE that's for $5 off 4 boxes of Kellogg's cereal. It has a Target logo on it, but it is a Manufacturer's coupon so you should be able to use it elsewhere.
This could make for some cheap cereal for some of you. I'll keep my eyes open for some deals to pair the coupon with. There are some deal ideas for Safeway chains HERE.
Thanks, My Frugal Adventures!
UPDATE: Looks like most stores are refusing it. I'll keep my eyes open for a deal on it at Target for you.
