smaller publishers tend to do that I think. The Irredeemable premier hcs are taller than deluxes and the Sixth gun and R&M hcs are even taller than that, just a bit smaller than a LE or an absolute.
But I would like to add that the R&M hcs are fairly quick reads so you might feel like you've spent £25 on an hour and a half of reading but they capture the tone of the show really well.
