Fantasy and Science Fiction Magazine, Kindle edition
Magazines are one of the staples of science fiction, with many authors getting their first break from them before going on to writing full-length books. Trouble is, they're almost impossible to get hold of. Newsagents don't carry them. Some bookshops do - not many, but some - but they never promote them, instead on the rare occasions that I've found them they've been hiding amongst a load of fashion rubbish. Just about the only place you can reliably get them is in sci-fi specialists like Forbidden Planet, but even then you have to make sure you get to the shop on the right day every two months lest they sell out before you get there - and you have to put up with going to Forbidden Planet too.
So when I saw that Amazon were doing magazine subscriptions on the Kindle, and that one of those magazines was Fantasy & Science Fiction I didn't really have any choice, I had to buy it. And given that Kindle magazine subscriptions include the first copy for free it's a no-brainer.
And I'm so glad I did it. My first copy was chock full of well-written short stories. If one or two were a bit sub-par that doesn't really matter, especially given that once I start paying it'll only be £0.99 a month, about a third of what it costs on paper - it's an absolute bargain, and you should subscribe immediately.
