The paperback version of Zen and the Art of Christmas Letters is for sale on Amazon.com at a special price. Get one for every person on your Christmas/Hanukah/Kwanza/Winter Solstice list.
In the event of a zombie or any other apocalypse, the paperback version is as edible as the fruitcake you sent your relatives last year.
You can gift the Kindle ebook as well but it has no nutritional value.
