There is a coupon for Kelloggs cereal at
You can print two coupons for $1 off 2 boxes of cereal.
Then there is a rebate for $10 Gift check by mail in the "New You!" magazine I picked up at the pharmacy in Kmart.
So you'd buy 4 boxes of cereal at $10 minus 2 $1 coupons for a total of $8 OOP...then you'd get a $10 rebate earning yourself $2...minus the cost of the stamp and sales tax. :)
It has been brought to my attention that the rebates are only good at the store where you picked up the magazine. So use your manufacturers coupon there and still get free cereal. You could also see if they will price match the Walgreen's ad. I'm not sure if Kmart does this or not.
