Shoppers queued outside Braehead before it opened on Saturday and were still there at midnight when it closed, according to general manager Gary Turnbull.
He said: "On a night when normally people are out with their friends in pubs and clubs we were very busy up to 10.30pm and then there were the really keen shoppers who were buying Christmas presents right up to when we closed at midnight.
"I expect the same will be the case today."
