“We want to make sure everyone has access to the items they need,” the website states.
“So we are setting aside the first hour of trading on certain days for our older and vulnerable customers, and for our brilliant NHS staff, carers and emergency workers.
“For older and vulnerable customers, this is on Mondays and Thursdays. For NHS staff, carers and emergency workers, this is on Tuesdays and Fridays.”
To help those struggling to get to the shops, supermarkets including Marks and Spencer have launched food boxes that can be ordered online.
These range from £15 to £45 and include essential items for different dietary requirements.
