It pays to search your King Soopers online account often, as new offers and digital coupons are added every week (usually on Wednesday.) This week, find a cool discount — get a Grande Frappuccino for $3 at its in-store Starbucks cafés. Depending on your order, it’s a saving of about 40% for the fancier Frappuccinos — more, if you add more syrups, toppings or fruit to your beverage. You must load the coupon to your card, which can be found under the category “Deli.” According to the fine print, the coupon can be used unlimited times through Saturday, June 3. (We’ve checked with friends and family and it’s on everyone’s account, as far as we know.)
