Dublin Chamber of Commerce has said retailers are feeling "cautiously optimistic" about their sales figures ahead of Christmas.
With seven shopping days remaining until Christmas, retailers are expecting a busy week ahead and think some consumers' spending decisions have been delayed this year.
Dublin Chamber of Commerce public affairs manager Graeme McQueen said the fact that Christmas Day is falling on a Sunday has impacted people's shopping decisions.
He said: "Black Friday was early this year so we've had quite a long lead-in to Christmas and people have delayed some buying decisions.
"Yesterday was a very busy day, and today looks like being the same."
