Irish online shopping increased by 20% in the last quarter.
The latest Retail Ireland monitor reveals that people took to the Internet as the value of Sterling dropped following Brexit.
It also shows that more shoppers are heading north of the border again looking for bargains.
Retail Ireland Director Thomas Burke says that Irish retailers are trying to be competitive but it's complicated: "Operating in that environment is going to be increasingly difficult for Irish retailers, on one side of it you have a consumer who is demanding to see the value of the Sterling decline in terms of prices and on the other side for a lot of retailers they have UK based suppliers, who are seeking price increases to offset some of their rising costs.
"So that leaves Irish retailers caught in the middle to a large degree and there is going to be an element of squeeze as a result."
