Amazon is building its largest-ever retail store in Orland Park, Illinois, spanning 230,000 square feet. The building's size rivals that of Target and Walmart.

Half the space will sell groceries, household goods, and prepared food, while the other half will fulfill online and in-store orders.

The Orland Park Board approved the project 5-2, clearing the way for construction on a 35-acre site, with a potential opening next year. 

The store will combine digital and in-person shopping, letting customers order different sizes or colors at kiosks and arrange heavy items for car delivery.

Amazon aims to use its Prime data to stock items customers want most and compete with big-box giants like Walmart, Costco, and Target.
