Functionality

Both web sites are hompages for stores where people can walk in, buy a product, and walk out, so these websites need to offer either vast amounts of easily accessible information or some sort of commodity not available in person.

Best Buy and Circuit City both feature all if not more products online than in the actual store. This is a convenience factor for the user back home. While they would have to drive to the store then walk around looking for the products, the online stores offer a quick alternative to look around and shop. This is also useful in case some products were sold out in the physical store, the online store usually has a warehouse stock as the source so the products are mostly available.
