Most Kmarts will be doubling coupons up to $2 this week. There is a limit of 25 coupons per customer, per day, but I have never had them count my coupons.
Bic razors are $4. There is a $2/1 mfg insert cpn. The $2 will double to $4, making the item free.
Pledge, toothpastes, shampoos, body lotions and washes, dog and cat treats, cleaning supplies, OTC meds, etc usually end up being free.
Their prices tend to be high to begin with, so keep that in mind. There are a Super Kmarts (similar to a Super WalMart or Super Target), but there are none in MN. The closest ones are in the Chicago area.
Monticello and Willmar stores are TRIPLING up to .75. Anything over .75 will be doubled.
