Sigh, here in Australia paperbacks regularly cost $23 and up. A lot of the popular YA novels are about $18 paperback, and I've been reading those lately, but in general they cost at least $22 unless it's something the book store is trying to get rid of. Hard covers are usually $35 and up. Damn you Australia! You've priced my freedom with expensive books! *rants* I mean, who needs freedom anyway? Lol.
But yeah, you should specify more information.
Meanwhile, the bit I'm more shocked by isn't the price, but the fact that you haven't been in a book store in a few years. Even when I have no money to buy books, I'll still go out specifically just to browse the book store (and have a coffee, the 2 go hand in hand with me).
I mean, I browsed the book store less than an hour ago (I should've been writing, I know, bad me, but I went out for coffee and McDonalds anyway so yeah...) when I couldn't afford any of the books I want.
But then I ordered one in... and some people will be pleased to know it was The Apocalypse Door by our very own Uncle Jim.

Release date was supposed to be 1st Jan, but I was told that it was released to stockists on Dec 18th, and that I had to order it in from America, but on the plus side it's actually available in Australia... I checked with the woman there and asked about any other UJ books that might be available, and they were all out of print and not available to Aussies. So I might have to order some off the Net if I like The Apocalypse Door.
But still, damn Australian prices!! (Yes I mean 2 exclamation marks!!)
