I love a chance to coupon stack at Target!
How about some free gum?
Mentos Up2U Pack – Single Pack (price may vary) – $1.25
$1/1 Mentos Up2U Pack, exp. 3/31/12 (SS 02/05/12 R)
and use $0.55/1 Mentos UP2U Single Pack Target Coupon 
Final price: Free after stacked coupons
They will lower the coupon to the amount of the gum so you will walk out with a freebie!
