Thanks for the explanation, Graham, DawnFalcon.
So fixed price means no more fictionwise sales for these books I guess. OTOH I could already not benefit of most sales because geographical restrictions prevented me from paying with credit card.
I do hope the books come back though, I _want_ to read my book!
Ironically, this book in paperback seems to be currently discounted at amazon :/

(I think I'll end up buying it in paper if it's not back on sale as an ebook on monday or something).
