The discount appears to be offered every month, throughout the baseball season — just check the bottom of a qualifying receipt for the offer’s availability and end date each month. King Soopers wants to take you out to the ball game “on the cheap.” When you spend more than $25 (in a single transaction), you can purchase up to 4 tickets at $17 each for select Colorado Rockies home games — while supplies last. To get the discounted tickets, you must use your SooperCard at check out. Then, exchange your qualifying receipt at any King Soopers customer service desk. (You should see the offer printed at the bottom of your receipt, so check first.) It might be wise to pick up some Cracker Jack and peanuts, since you’re already at the grocery store!
