Check out this scenario using all sorts of coupons for Nabisco 100 Calorie Packs! You will need to buy 4 items to use all the coupons I have listed.  You will never be using more than one manufacturer coupon per item.  The two B1G1 FREE coupons count toward the 2 items you get for free, the $1.00/2 coupon counts towards 2 items that you are paying for, and then the Target coupon stacks on top. Make sense?
