Use store coupon in new ad that says "3 day sale" on the front.
Pop Tarts coupon is on the back page and these coupons are good for 7 days.
Store coupon is for $1.00 per box with a limit of 2 per coupon.
Use $1.00 mfg. coupon off 2 boxes from the booklet inside specially marked boxes of Kelloggs cereals (I still have some booklets left from the Back to School rebates last September).
That makes it 50 cents a box!!!
Store coupon does say $10.00 purchase is required but my store does not enforce that.
