If you own a Nook you'll want to read this: BBC News. As of March 15 Nook will cease selling e-books in the UK, and the UK versions of the online store and app will no longer function. Barnes & Noble have made a deal with Sainsburys to make sure users can still access purchased content. If you have bought anything, you'll need to take action by the end of May to still access it. Keep an eye out for an email with instructions.
