I paid the $10 for the top tier not because I particularly wanted the novella, but because from past experience, the HB e-book bundles usually go above $10 for the average price anyway by the time they add the extra mystery books.
So I figured I might as well splurge a bit, potentially save if it climbs higher, and get a bonus at the same time.
I did already own LMB's Chalion book which would have been the main draw, and don't like Neil Gaiman's novels nearly as much as I like his short stories and comics (and AG is a particular unfavourite), and I think I already have that particular Coelho from the time there was a 99 cent sale on 12 of his novels, but I figured it was worth getting the entire bundle to encourage HC to potentially offer more stuff DRM-free and discount bundle pricing in the future.
But I am interested in the Mezrich casino-hacking story (although I wish it were a non-fiction version of such). And I hope they have something nice released as the bonus(es) for next week. I've probably jinxed it now.
