The Kobo daily deal rigmarole--backing out of the sale price and then applying for the deal--did not work despite what they told me. The correct price drop did occur and that's that.
So far, results are reasonable, and it's a kick having a book in the top 100 of any store. In a couple of categories, it's even in the top 10.
Interestingly, in the Amazon U.S. store, despite having sold well over 100 copies today, the book ranks only in the 24 thousands. A tribute to just how many books are for sale on Amazon these days. Used to be that one could attain a much better rank with far fewer sales.
(Edited to correct my error, since the current KDP sales page does not show marketplaces the way the old one does. Checking that, I see the U.S. sales, while still ahead of the worldwide sales, are not so many units more than, say, Australia. Thus the ranking this morning at 35k in the U.S., while still unfortunately proportional to the vast U.S. store, is not for every Amazon sale.)
I remember many years ago working for a company that had a big publicity push planned for a certain day. Then a world leader was assassinated that day. So much for plans. I don't think the dear Queen's death today is likely to affect my international BookBub today, but the title of my book relates to death, so who knows?
Edited to add more details and then again to clarify them.
