I did not say that Cheney would not sign books at Sam's, just that you should not count on it. And although bookstores DO have sales. when they have signings, the books to be signed are rarely on sale, if ever. When we have mobs of authors here at the Miami International Book Fair, the books available for signing are all sold at full retail.
They are often discounted after the signings are over. I imagine that the publisher feels that since they paid for travel and lodging, they deserve their full price. I can't say that I disagree with that premise.
When I want to read a book, I decide whether I am likely to read it more than once. If not, I check out the library, and read it at no cost. If I do think I will read it again, or it is not available at the library, I check out Amazon, and buy it used. I have yet to get anything other than like-new books from Amazon or one of their affiliates, usually at less than a fifth the retail price.
When I buy things, I am unconcerned with the national economy. My own personal economy is far more important to me.
Now I see where Cheney badmouthed pretty much everyone, including even Condi Rice and Colin Powell. And he says not a word about how a lack of proper planning turned the invasion of Iraq unto a godawful mess.
Cheney, as we all know, does not need the money, though he probably thinks he does, just like Murdock thinks he needs his fifth billionth dollar. What he wants to do with this book is to get the country to absolve him and perhaps Rumsfeld of the blame for starting a war on false pretenses and letting everything run amok. And I don't think that history will absolve him of his supreme dickheadedness.
Good luck at finding Cheney's book, discounted, at a Sam's near you.
