The Interactive Media in Retail Group (IMRG) predicted consumers would part with up to £153m on Christmas Day, a period traditionally absolved from festive spending fever.
High Street stores are also enjoying good business. The Mirror reported up to £2.5bn was spent at packed stores and shopping centres across the UK yesterday alone.
The British Retail Consortium estimates £5billion will be spent in the sales this week, though today it warned retailers were bracing themselves for a difficult year ahead, with the majority predicting a decline on this year's levels.
