Brick and mortar
A "brick and mortar" store is a retail store or chain store with a actual building and inventory available on site for display and immediate sale in a shopping district. Thus a brick and mortar store has substantial overhead as well as being subject to sales tax and other local taxation. A brick and mortar store must be staffed during the hours it is open.
Brick and mortar stores are frequently contrasted in terms of overhead, selection, and service with online sellers which may, in the extreme iteration, have no physical location, infinite selection, be available 24/7, have only IT employees, and pay no taxes.
