White Castle, ever considerate of its customers, offers air fresheners as part of a new promotional event. They are free for a limited time to any customer who purchases a sack of 10 hamburgers.

In addition, nearly 3,000 cab drivers in Chicago, Detroit and St. Louis will receive a White Castle Air Freshener Kit that includes not only a free White Castle air freshener, but also a coupon for five free White Castle hamburgers.

The air fresheners are available in three fun designs and scents—lemon- line, vanilla and outdoor breeze. Offer is available for a limited time only while supplies last at White Castle restaurants.
