Shoppers were out in force on London’s Oxford Street as usual, with some stores hiring extra security
Online retailer Amazon says it had its biggest sales day in the UK as shoppers rushed to buy bargains on Black Friday.
The UK version of the website sold more than 7.4m items while other retailers had problems with web sales due to huge demand.
Retail analysts said online sales were estimated to have passed £1bn on a single day for the first time.
The discount day originated in the US, traditionally kick-starting the Christmas shopping period.
Argos confirmed it had experienced delays on its site after “extremely high levels of visits”. John Lewis said its site had been down for a short time in the afternoon.
Last year’s Black Friday saw shoppers in the UK fighting over bargains in some stores, leading some retailers to hire extra security staff over the weekend to prevent a repeat.
But analysts said this year many shoppers had chosen the internet over the high street.
