After Khizr Khan pulled a pocket-sized copy of the U.S. Constitution out of his jacket at the Democratic convention, sales have spiked on Amazon (AMZN).
“Have you even read the United States Constitution? I will gladly lend you my copy,” Khan said during his Thursday speech.
On Monday, $1 copies of the pocket Constitution were the No. 1 best seller in the site’s history section, and No. 2 in books overall, beaten only by the latest Harry Potter book. Free pocket-sized copies of the Constitution are also available from the American Civil Liberties Union website until Election Day by using the coupon code “POCKETRIGHTS”—a deal announced on Twitter (TWTR) Friday.

The U.S. Constitution is one a several books available for free on Amazon’s Kindle for those who prefer to consume literature on e-readers.
