Right now Walmart has the 10 oz. Kellogg's Cinnabon Cereal for only $1. In the 8/15 Parade Magazine insert (from the Sunday paper) is a coupon good for Cinnabon products (including the cereal) for $1 off = FREE Cereal!
There is also a printable coupon HERE and HERE good for $0.75 = $0.25/box.
*My local Walmart (Clarkston, WA) is currently out of the cereal but they have some on the way. Of course, Walmart prices vary between stores so not all stores may have it for $1.
**Some boxes have a "Try Me For FREE" Mail-in-rebate form on them which would turn this into a $1 moneymaker.
