Wow! I am assuming you have a Super kmart? You did great! I remember the days when Meijer did super double coupons- they only doubled $1 coupons up to $2 and I would get so much food/hba for so little. I lived in the store those weeks(or at least it felt that way, lol!).
We do have a Super Kmart. My husband loves it when they do their doubles. My pantry and freezer are always full of goodies as he puts it.
