Several Penneys stores in Dublin and Cork will remain open overnight tomorrow night.
Dundrum Town Centre, the Blanchardstown Centre in Dublin and Cork's Wilton Centre will offer late night shopping this Friday.
The outlets will open as normal tomorrow morning, but will not shut until closing time on Saturday evening.
The company has also committed to keeping customers up to date with queue times on social media.
A number of Penneys stores previously stayed open for 24 hours when shops first reopened earlier this month.
Newstalk reporter Kacey O'Rirodan said it took her 40 minutes to get into the Blanchardstown store after joining the queue after midnight.
One shopper voiced concern over people "climbing over each other trying to get at stuff" in the store.
However, Penneys says "nothing matters more to them" than the health and well-being of employees and customers, and strict social distancing rules have been implemented across their stores.
