Trump’s more than 100,000 copies sold is 50 times more than the approximately 2,000 copies former New Jersey Gov. Chris Christie sold of his latest book…Trump’s book is selling at $74.99 for a hardcover copy and $229.99 for a signed copy, while Christie’s is retailing in the mid-$20s per copy, so the feat is even more impressive considering the cost differential between the two.
