Into the aisles

Spirit set up their temporary walls to force everyone to enter through the display area before opening the salesfloor up to the main costume/decorations section. Clearly, Spirit didn't use much of the Sears space, and that allowed them to get creative with their layout. (It's also possible that they set it up this way to close off Sears' old checkout desk that was straight in front of the entrance, if Sears left that when they closed.) Most of the store is in what was once the jewelry and Land's End sections of the store, basically the front left corner, with the big displays on the left and the main shelving on the right.
