Here’s a copy of their policy: (Just be sure to read your coupon. Some manufacturers prohibit store coupons to be used in conjunction with retailers coupons)

  Target’s Coupon Policy

We accept two kinds of coupons: Target-issued coupons and manufacturer-issued coupons.

We’ll accept one Target coupon and one manufacturer coupon for the same item, unless either coupon prohibits it.

We can’t give cash back if the face value of a coupon is greater than the purchase value of the item; in that case, we’ll adjust the value of the coupon to equal the price of the item.

We can’t accept coupons from other retailers, or coupons for products not carried in our stores.

All valid coupons should be presented to the cashier at the time of sale.
