Uh huh.
I find the situation both frustrating and reassuring... frustrating as a reader with favourite Aussie authors, reassuring as an Aussie writer who's winning more customers because of the whole fiasco...
OTOH, I did find some decently-priced ebooks on the Borders site. Not that it's easy to navigate, and I hate that 'sort by price' isn't available!
