Today when I picked up the mail, I found a flat box that looked like a book shipping container. I hadn't ordered any books except from Amazon and they don't use this type packaging.
When I got back to the house and opened the package, it was the first volume of a set of woodworking books from Woodworker's Journal. If I wanted the book, all I had to do is to send them $9. If I didn't want the book, I could return it using the enclosed return shipping label. I had not ordered this book, or even knew of its existence.
As I recall, anything sent to you or me, without requesting it, is ours to keep. At least it used to be that way. I pondered that for a about 5 seconds, and repackaged the book and put the return label. I will go out tomorrow.
Look for the subscription prices to go up to cover the losses on this advertising campaign.
