Edit: My print books still show the following "Available to ship in 1-2 days. " on the product page. Not sure if a different message is displayed at checkout.
Same here. I got that email this morning, so I went into Amazon and ordered one of my paperbacks to see how it would go. Said the book would arrive sometime next week. With Amazon taking on 100,000 new workers in the coming days, I'm thinking they've got this handled. It's the supplies they need to worry about.
On another note, I went through the process of ordering and was going to have it sent to a Yellow Box just down the road, but when I saw the shipping on it, I just about flipped. I don't remember the shipping being $10 to send a book to the Yellow Box. As a matter of fact, I remember it being less than the standard shipping.
