The National Geographic Store is having a limited-time sale on the deluxe hardcover eighth edition of the National Geographic Atlas of the World. Normally $150, it’s now only $60 — at least until midnight tonight. The reason for this sale is obvious: the ninth edition of the Atlas is coming out in October, so I suspect they’re trying to clear out stock of the previous edition. But if you don’t mind owning that previous edition, which came out in 2005, and getting it at a substantially reduced price, you might want to get a move on. I’ve made my own order already.
