Target now price matches a price in a published competitor's ad.
Target does not double any coupons. However, they have in store coupons you can print from HERE
Some of these coupons print out as a manufacturer's coupon and some as a store coupon. If it is a store coupon, you can "stack" that store coupon AND a manufacturer's coupon and use them on the same item.
You can also sign up to receive mobile coupons. You will receive a text message with a link to your coupons. There will be a barcode that will show on your phone for the cashier to scan and redeem you coupons. You can sign up HERE.
Something else that Target has been doing is Gift Card rewards. They have many of these in their weekly ad, but there are also some instore that they do not advertise. For example, right now there is a list of items .. if you buy 2 of any of those items, you receive a $5 Target gift card. There is toilet paper, paper towels, Tide detergent, Bounce dryer bars, and many other items.
