But Duke, the listed company's majority shareholder, has consistently refused to say exactly what percentage online sales now constitute or the dollar amount due to "commercial sensitivity."
Duke said there was considerable potential for on-going growth in online sales and he was continuing to look at ways to deliver that.

Overall, Briscoe's sales rose 2.9 percent to $167.4 million in the fourth quarter despite tough trading conditions that led to aggressive discounting.
For the 13 week ended Jan. 25, homeware sales rose just over 1 percent to $113.1 million while sporting goods sales lifted 7 percent to $54.3 million.
