Sears was way ahead in their store design, once they started building stores, and location scouting. They were one of the first do automobile centered stores with large parking lots, even in the teens and certainly by the 20's, in outer areas of cities and by the 30's and 40's were very creative with store design - one of their Washington DC stores and an LA store come to mind (there is an excellent article in the Journal of the Society of Architectural Historians on just this subject). By the late 50's they started locating in malls because the stand alone stores didn't attract as much business as well as it being easier to have someone else do the initial development - it was hypothesized that this period is when their retail reach started to wane along with their design innovation which had been in both interior and exterior design, site and space planning as well as merchandising within the stores.
