Bookseller Barnes & Noble is to close Nook, its UK eBook operation.
The announcement comes after the company yesterday reported sales of Nook dropped by a third to $51.7m (£36.4m) in its third quarter, ending January 2016.
Overall, Barnes & Noble reported sales of $1.4bn, down 1.8 per cent.
It said yesterday losses on the product contracted during the year, thanks to the company's efforts to rationalise costs.
The US company said in a statement: "Effective from March 15, 2016, Nook will no longer sell digital content in the United Kingdom.
"The Nook Store on Nook devices sold in the UK, on the UK Nook Reading App for Android, and at nook.com/gb will cease operation."
UK customers will be transferred to Sainsbury's, the company said.
