In other mall news, Cinnabon is moving into the long-empty space next to Popeyes. The Core clothing store, which exited Westfield Montgomery two years ago, is making a comeback in the Nordstrom wing. And here’s a perk for online shoppers: A wall of Amazon Lockers will be installed next month near Forever 21. Not familiar with the concept? Amazon Lockers are self-serve “mailboxes” where you can drop off a package or receive a delivery at the time of your convenience. All you do is schedule the pickup or dropoff online, then Amazon sends you a locker number and a private code to open it. No more waiting for the UPS truck or worrying about porch pirates.
