Lidl is re-opening its Fortunestown store this morning after four months of construction.
It was destroyed in March during Storm Emma looting.
Nine people were arrested after the event, which was captured on social media.
The newly re-built store has increased in size by 70%, from 997m2 to 1698m2 in floor space.
It also has 50% more parking spaces, additional tills, wider shopping aisles as well as a new training room facility and extended welfare area for employees.

Lidl's area manager Denise Cullen said: "It was something that nobody expected would ever happen - it made global news at the time.
"It was a shock to us all - but as a business, number one for us was the safety of the staff.
"First protocol was to contact all the staff: to make sure that they were OK, that they knew not to approach the site.
"The matter was dealt with by the guards".
On redeployment of workers, she said: "The incident happened on the Friday and by the Monday everybody was redeployed in a store that was best for their own location".
"Everybody is so excited to be back - we're bigger, better, a brighter store for the community here".
