Consumers here will spend around €25,000 a minute online during Black Friday, AIB has estimated.
Nearly a third of that minute-by-minute spending will go on clothes, the bank forecasts, up 232% on a normal day.
In raw numbers, the bank expects around 135,000 clothing transactions to take place across the day online, or two every second.
Bucking the stereotype, the research finds that men are the biggest clothing spenders on Black Friday, shelling out an average of €90 per transaction, compared to €77 for women.
"Our data shows that consumers are increasingly choosing online when it comes to grabbing a bargain on Black Friday," said John Brennan, Head of SME Banking at AIB.
"While this ensures more choice for consumers, it's also important to consider the impact that buying from abroad can have on the climate. Shopping locally where possible ensures we are minimising our carbon footprint."
"It also ensures we are supporting local Irish businesses who have invested in their online shopping services and have faced challenges over the past two years as a result of the pandemic."
After clothes, AIB forecasts that electronics will be the next big spending category, with €4,400 set to be spent every minute on gadgets, nearly twice the normal amount.
Other popular categories include hardware, health and beauty and jewellery the bank said.
Mid-morning seems to be the preferred time to complete online shopping on Black Friday, with the peak period of transactions taking place between 11am and 12pm.
AIB has urged consumers to take great care when buying online because of a rise in internet-based scams and fraud.
The data is based on over a million transactions on AIB cards on Black Friday last year.
