If you haven't done the Target Kashi deal yet, you can go here to get a $1 coupon off of Kashi cereal (Thanks It's Hip 2 Save).

This would make the cereal .88 after the gift card deal....and if you have the walgreen ad, you can pricematch them at $2.50 so would make them .50 each! I would take them to guest services and do it there, because they are unable to do it after the transaction since refund value is only $1.88 after the gift card offer.
