When a retail store provides a major customer aisle that begins at the entrance, loops through the store (usually in the shape of a circle, square, or rectangle), and returns the customer to the front of the store, the store is said to have a loop layout. We believe that the Loop store layout is the best because it encourages browsing. Because it promotes browsing, the different angles allow customers to see everything as they walk along the path. Because you can see everything, this layout allows for many impulse purchases.
