So you are an author. You check your book’s entry on Amazon.com. You see a review. It is not good. Someone bought a copy of your book and it was flawed. You want to make it right.
What do you do? You promise the reviewer that you will send a good copy via overnight delivery. Then you realize that it is Christmas Eve, the reviewer lives in Ontario, Canada, you live in Ohio, and there is a massive snowstorm between the two locations. The delivery services cannot deliver, bookstores are closed, and time is running out.
Then what do you do?
Perhaps what Whittenberg University professor Dan Fleisch did : You deliver it yourself.
