There's a new Target mobile coupon available for $10 off a $50 grocery purchase (food and beverage) that is valid starting Sunday! Text FOOD to 827438 to get the coupon which is valid 5/18 - 5/24/14. The same coupon should also be in the Target ad on Sunday if you don't have a mobile device.
The coupon excludes alcohol, baby food, nutrition shakes and bars, pet food, Target Cafe and Starbucks Cafe.
Keep in mind that you should be able to use the paper coupon from the ad on Sunday at Harris Teeter and possibly Lowes Foods as a competitor's coupon. Neither store will accept the mobile coupon as a competitor's coupon.
