Traders in Birmingham have experienced record customer spending since Christmas.
Bullring saw its best day ever on Wednesday - the day that the Mailbox witnessed the longest queues in its history before the shops opened.
Yesterday's trading figures, which were not released last night, were also expected to show a bumper Christmas for the city's top stores.
Selfridges experienced its best day of trading ever on Boxing Day and almost 250,000 shoppers visited Bullring the following day - a five per cent increase year on year.
This follows a bumper Christmas period for Birmingham's top shopping centre, which saw footfall grow by 15.5 per cent year on year in the week before Christmas.
Bullring general manager Tim Walley said: "Bullring goes from strength to strength in our fourth year of trading. This is great news for Birmingham, demonstrating our strength as the second city and as a major retail destination."
Kevin Breese, general manager of Harvey Nichols, in the Mailbox, said: "We had an awesome day on the Wednesday.
"We had people queuing up around the side of the Mailbox before we opened, which were probably the biggest queues we have ever had.
"We have been open until 8pm and have been busy right up until the end of the day.
"We have had a fantastic few days, which just goes to show that Brummies really do love their January sales."
More than 2000 transactions were processed at Selfridges before 10am on Boxing Day - 140 per cent up on last year. Also, more than 250 people queued to get into the store before it opened.
