It is understood that the change was made in all stores. In Plymouth, Lee Mill and Roborough stores kept shoppers from reaching levels by placing boxes of chocolates in front of escalators, with a security guard guarding the area.
Tesco stores with all items on one level did not block out areas, meaning clothing, household items and electronics could still be purchased.
TeessideLive reports that rival chain Asda has kept its mezzanine level open, selling similar items to the public.
Asda explained that because it was seen as a go-to retailer, it “doesn’t have to close the aisles and can continue to sell our regular product lines”.
It is now understood that the upper floors of Tesco supermarkets reopened on Saturday morning, with all items on sale.
A Tesco spokesperson confirmed the change: “Our mezzanine levels are once again open to customers in all of our stores.”
Tesco also recently updated its Christmas policies and deliveries.
Tesco has published its Christmas delivery slots for Delivery Saver customers, with reservations for other buyers available from 7 a.m. on November 20, Birmingham Live reports.
Offers were also launched for Black Friday, including electrical goods, toys, books and DVDs.
The supermarket giant said: “There is always a high demand for our online service, so we encourage you to buy in-store if you are able to, where we have a number of security measures in place. .
“To help more people shop in-store at quieter or more convenient times, we have extended the hours of operation of many of our stores, although most remain closed overnight.
“We have more than doubled the number of online slots to 1.5 million every week. This is to help anyone who cannot shop in-store – especially our most vulnerable customers – to access our online service.
Tesco now has 40% fewer promotions as it shifts to a “low prices every day” strategy and rolls out more exclusive discounts to Clubcard holders.
