If you go to http://www.magazinesondemand.co.uk/digital/nme/,
there is an offer for a free digital issue of NME.
However, if for the second question ("How frequently do you purchase NME?"), you choose options 3 or 4, you will offered a free 6 week digital subscription to the magazine! It says there are 5000 available so don't miss out! You must also say you are 18-24.
I've done it and it seems quite good...you have to download an application and then that lets you download and view the magazine!
