A week ago I applied for a US-only bookbub on a title which had an international-only BB in January. Accepted yesterday.
This is the carefully-crafted comment I included with my submission:
You ran an international (non-US) Featured Deal for this book in Jan this year. Now I've set it to perma-free, and am hoping to promote the first in this series to US readers.
Yep, took all of thirty seconds to come up with that. I think we can agree the magic handshake is not in whatever you put into the comments box.
Anyway, in Jan this was a 99c featured deal, reduced from 2.99. Now it's been perma-free for at least a month, so there's no actual price reduction or special offer or anything. (Another myth dismissed?)
I do have 32 reviews for the US edition with an average of 4.3, and it's pretty well regarded on Goodreads as well, but I've had featured deals on books with one review before now. As others have said before, reviews don't seem to matter at all.
Just sharing all this to help others unlock the mysteries of Featured Deal acceptances.
My personal theory is that acceptance depends what kind of slots they have available... ie what kind of books are already lined up. If they have a heavy-duty scifi space opera as one featured deal, then having a lighter scifi novel with a female protagonist on the cover as the second deal could widen the appeal of that daily email. It's all about getting subscribers to click...
The other thing was, even though I just applied for US-only, in the acceptance email they said they'd love to include international as well. I said yes, naturally.
Now I just have to price-match amazon.in
