You just want one copy? It is quite hard to get hold of nowadays, Smiths used to sell it years ago when I first started reading it but that was back in the 1980s and it was called something different then!!
A good indie newsagent should be able to order a copy easily enough.
It only costs £33 a year to subscribe and is well worth it to keep abreast with technology.
From next month you'll be able to download it if you have an iPad apparently.
