Do Tesco have competitors?

Tesco have expanded their business to the extent where they are not only in competition with other supermarket retailers such as Asda and Sainsbury’s but they are now in direct completion with companies such as Argos and Amazon. This is a major step for the company which was once just a grocery store. I feel as though Tesco’s have actually come into their own and managed keep up by providing the online site as well as banking, insurance and a mobile supplier. All the services that Tesco’s now provide for their customers makes them a store most people in the UK can’t avoid.
