OMW Hardcover, Out of Print
It looks like all the hardcovers of for Old Man’s War are gone: I can’t find anyone selling it online (well, for less than $39.27, which I don’t suggest you pay), and since I don’t think I actually ever personally saw it in a bookstore, I don’t suspect there are many hanging around the shelves, either. It’s still (and amply) available in trade paperback, of course, but if you wanted it new in hardcover, with the Donato cover and everything, well, um, sorry.
Patrick’s currently in Ireland (and it’s 1:30 am on a sunday morning) so I can’t ask him at the moment, but I’m curious to know what the sell-through was — that is, how many of the books that were printed were actually sold, rather than returned and then turned into remainder table fodder. The scarcity of the hardcover suggests to me it sold through pretty well, but having never been to this point with a book before, there’s lots I could be missing there.
If you do want OMW new in hardcover, this is one option remaining to you, which is to get a Science Fiction Book Club edition. But be prepared to wait a couple of weeks; the Web site says it’ll be available on March 26th. Patience is a virtue, especially when you have no choice.
