Only the publishing Gods understand why some books go on sale and others don't.
Out of the blue, I noticed today that Amazon has slashed the price of Conspiracy Theories & Secret Societies For Dummies down to a paltry $11.29. I will confess that's cheaper than I can buy it from the publisher myself. And if you order over $25 worth of stuff at one time, the order is eligible for free shipping.
They are also doing a package deal with Templar Code For Dummies, both books for $24.88.
I have lots of time to stare into the intertubes today.
My doctor informs me I have pneumonia.
This thrills me to my very core.
