Supermarket Tesco has said that online shoppers will have their deliveries capped at 80 items from now on.

In an email to customers it said that the aim was “to increase the number of customers we can safely deliver to”. It is the latest move by supermarkets to safeguard people and supplies during the coronavirus pandemic.

Supermarkets will also use a government database of 1.5 million vulnerable shoppers in England to help prioritise delivery slots.

Tesco has already limited all products to a maximum of three per customer, whether they shop online or in stores. Announcing the latest measure, the retail giant said that online orders already placed were unaffected unless customers make changes to them. Anyone who edits an existing order will become subject to the 80-item limit.

Tesco added: “We’re at full capacity for the next few weeks and we ask those who are able to safely come to stores to do so, instead of shopping online. This will help us to free up more slots for the more vulnerable.”
