There's those 99p copies of classic novels in The Works if reading from a screen is no good. Not sure if they are in other shops, but the formatting looks right (proper, fuzzy printing and all).
Yeah my town isn't a good place to be if you're a writer or avid reader of science fiction or fantasy. We have no bookshops (seriously, we used to have one but nobody went there so it shut down), the only place you can buy new books are F-ing ASDA (and their selection is woeful if you're into anything other than big new releases or non-fiction books about TV shows) and WHSMith (which is better enough that all my book purchases in recent years have come from there, but it's still not the best).
And the local library, in terms of fantasy and sci-fi... there's not too great a selection there either. In the entire building, fantasy and sci-fi take up a couple rows of shelves and that's it.
So yeah, my best option for buying books is either Amazon or WHSmith and WHSmith doesn't carry H.G. Wells. I've checked, he's nowhere to be found. Lots of "classic" authors, no Wells.
