On April 29, 24 bookstores in the Chicago, Ill., area will celebrate Independent Bookstore Day with the #MyChicagoBookstore Challenge. With an initial purchase of at least $25, customers can pick up a #MyChicagoBookstore carabiner and their first luggage tag at any participating store. From there, customers will receive a luggage tag at each successive store they visit, with no additional purchase required. Anyone who collects 10 luggage tags will receive 10% off at all of the indies participating in the #MyChicagoBookstore Challenge for the next year, and those who make it to 15 stores will receive 15% off. Customers are also encouraged to take photos of themselves during the challenge and share them on social media for a chance to win more prizes. The #MyChicagoBookstore Challenge is sponsored by the Chicagoland Independent Bookstore Alliance. More info can be found here.
