You can join the Kashi Community and get access to print a coupon to Save $2 on any Kashi product, it's got a rolling expiration date so it expires one month from the date you print it. Be sure that you print this coupon twice - this is the typical print limit on all coupons that have "bricks" in the URL (just hit the back button).
Note: These products are often on sale for $2.50 at various stores. W/coupon, that makes them $0.50ea. --great deal!
