I have to admit, I miss p-book sales sometimes. I used to buy a
lot of books off of Chapters' regular "buy 3 get the 4th free" sales... which had the advantage of being store-wide.
Still, I
like Agency. IMHO Agency is the only thing stopping an Amazon
monopsony in the ebook space, and, for the most part, prices for the ebooks I want to buy are consistently a bit cheaper than the price for the closest paper format (MMPB often, TPB growing lately.)
In addition, sales, when they do happen from the publishers, can be astonishing. I picked up every Jim Butcher book I didn't own already in epub for $2.99 per book. Even Battle Ground, which, at the time of the sale, hadn't been released yet.
Yesterday, a four-book bundle of Sarah J. Maas' work went on sale for $3.99. ($3.59 with Kobo VIP.) It's back to the regular price now... $46.43 with the VIP discount. (You can still get the sale @ Amazon Canada if you're interested.)
All told, I'm happy with the current situation. I'm spending about the same as I would have for p-books, in a format that I greatly prefer, and sometimes, I'm paying a lot, lot less. (I would never have gotten Butcher's library for $2.99 a pop in the p-book realm. Never, ever happen.)
