Thousands of shoppers were left disappointed last year when delivery slots for Christmas grocery deliveries from Tesco and other supermarkets were snapped up minutes after they had been made available online.

Customers with a delivery pass from a supermarket have a significant advantage over those that do not, as many supermarkets offer them early access to the booking site.

When do the major supermarkets open their booking slots for 2019?

Asda

Booking opens on Monday 18 November.

Delivery pass customers can book from Wednesday 13 November.

There is a minimum basket charge of £3 for orders under £40.

Tesco

Tesco’s system opens new delivery slots day by day, three weeks in advance.

This means the delivery slots for Friday 20 December would become available to book online three weeks before - on Saturday 30 November.

Customers with a delivery saver pass can start booking online from Wednesday 27 November.

Morrisons

Morrisons’ delivery slots for 20 to 24 December open on Wednesday 27 November.
