Whew! I thought my wish-listed book, Iain Gilchrist's two volume The Matter with Things, for $148 was steep!
And that book clocks in at 1500 pages, so you're paying a dollar a page, which is normally steep, but depending on how much you like the writer and his insights, it could be a value. I just checked outside of Amazon on mine, and I'm glad I did, because the independent sellers there often price-gouge, and it looks like Abe Books has good quality paperback versions at much more reasonable prices.
ETA: wait, I think it would be a
dime a page, not a dollar. So that's almost a steal.
ETA again: Or is it ten dollars a page? Why can't I do this math?
