Endless aisle refers to the practice of retailers offering additional inventory online that is not available in their physical stores. This allows consumers to browse and purchase items that may not be in stock at their local store or even in the same country.

Endless aisle is especially beneficial for customers living in rural areas or those who are unable to physically travel to a store. With endless aisle, customers have access to a vast selection of products, making it easier than ever to find exactly what they're looking for. As ecommerce continues to grow, endless aisle is becoming an increasingly popular way for retailers to offer more options to their customers.
