According to the DFRPG Kickstarter update:
"We're alerting the Dungeon Fantasy Roleplaying Game supporters first: Warehouse 23 now has fewer than 100 copies of the boxed set in stock, and these are the last that we expect to have for the immediate future. If the game is reprinted, we will make an announcement, but at the moment, we have no plans for a second printing."
So, if you want one . . . get one soon. It's a very good product. Hopefully it'll be possible to get the whole set's books in POD as a set, soon, since the boxes will be gone. I have two myself, and I honestly prefer it as my go-to GURPS ruleset for our game.
