Chicago pizza chain Giordano’s is throwing a bone for those struggling with ever-rising gas prices. Starting Friday, May 22, the chain is launching its new “Summer Savings – Save a Gallon” promotion that takes the average price of a gallon of gas in Chicago off any pizza order. Here’s how to save on your next slice. The promotion is only available for members of Giordano’s loyalty program at participating locations nationwide for dine-in, carryout and delivery orders. Third-party delivery orders are excluded. This includes those who choose to sign up for the loyalty program this summer. The offer applies to any order including at least one Giordano’s pizza with a minimum order of $15. How much can you save on your Giordano’s order? Every Monday throughout the summer, the pizza chain will update the discount based on the current average cost of a gallon of regular gas in the city of Chicago. Discounts will reflect gas prices published by AAA.
