I don't know what sorcery brought this about, but there's only five hours left on the sale, and here's what it means. You can get On The Rain-Slick Precipice Of Darkness 4 - which just came out, mind - for $2.49. Precipice 3 is also 2.49. Here's where it gets kind of crazy.
You can get both of them, together, for four dollars. No, I don't know why. Presumably, the manager is "out of town."
