The increase in households where both adults work outside the home, combined with the convenience of shopping for and buying products and services online, has decreased the number of customers going to retail outlets, as consumers can access the same information about products and services without paying for gas, parking and other costs, thus saving them time and money. "Today’s consumers lead busy lives and and Mortar shopping takes time. Often it is a task. Consumers find researching and shopping on the Web far more convenient than brick-and-mortar visits." Brick and mortar businesses are not limited to having a physical presence only, they may also have an online presence such as Tesco, who offer an online grocery service as well as a brick and mortar retail presence.
