Retail Ireland has noted a slight rise in average household spending during this Christmas season, anticipating a surge of shoppers for the upcoming January sales. While many retail outlets will operate under limited hours today, some supermarket chains like Tesco and SuperValu will reopen. However, others, including Aldi and Lidl, will remain closed until tomorrow. Public transport options will be minimal today, with no DART or Iarnród Éireann services, while bus services will run on a Sunday timetable, encouraging travelers to check schedules in advance.
