Supermarkets are urging shoppers not to buy more than they need amid concern over coronavirus-linked stockpiling.
In a joint letter, UK retailers have reminded customers to be considerate in their shopping, so that others are not left without much-needed items."There is enough for everyone if we all work together," it adds.
It comes after some shops began rationing the sales of certain products to avoid them selling out completely, reports BBC.
In the letter, the retailers say online and click-and-collect services are at "full capacity" and staff and suppliers are "working day and night to keep the nation fed".
The retailers say they are working "closely" with government and suppliers to make more deliveries to stores so that shelves are well-stocked.
Items including toilet paper, hand sanitiser, pasta and tinned foods are among those that have been in short supply.
