Here in New Zealand (and probably many other countries) we get each book in Brandon Sanderson's Stormlight Archive split across two volumes. At first I was neutral towards it, but due to circumstances beyond my control, I ended up with the fourth book in just one volume. This thing is gigantic! I'd find myself having to read in much shorter sessions than I normally would due to my arms getting tired. In the end, I had to switch to the ebook for purely ergonomic reasons.

I think I did end up paying more for the books that were split up, but to me it's worth it. I understand that won't be everyone's experience though.
