Large superstores which operate businesses of types that are described in the list of essential retail outlets may continue to operate those businesses but only selling essential goods and services. If you do open your business then you must ensure that you put in place measures to ensure that social distancing of both your workforce and customers is maintained. If this is not possible then you will not be able to open. You must also ensure adherence to hygiene guidelines. You should only travel to and from your place of work to provide those services.
