On December 21, 2011, Barnes & Noble accidentally shipped 1500 copies of The Fault in Our Stars before the release date to people who had pre-ordered the book. Green released a statement saying, "Mistakes happen. The people who made this error were not bad or incompetent people, and they were not acting maliciously. We all make mistakes, and it is not my wish to see Barnes and Noble or any of their employees vilified." Many people who received the book pledged not to read it until its release date, January 10, 2012, or discuss it until the next day, January 11, as per a request of Green's not to spoil it for other readers. Most kept to this promise, leaving the experience untarnished for those who got the book on the intended release date.
The book rose to #84 on the Amazon.com and Barnes & Noble bestseller lists in June 2011 shortly after its title was announced. Green promised that every pre-order would be hand-signed by him, requiring him to sign every copy of the first printing. He proposed that the general public vote on the color Sharpie he would use to sign the books, resulting in him signing the 150,000 books with a variety of Sharpie colors, each in proportion to the amount of votes received for that color. However, some people who ordered from international booksellers received unsigned copies because those bookstores, including Amazon UK, underestimated how many books they needed and ordered more after the signing was complete, but Green agreed to fix this problem, telling people with unsigned pre-orders to email him so they could be sent a signed bookplate. Many fans submitted their book cover designs to various outlets including Tumblr and Twitter, tagging Green in these posts so he could see them. The sizeable number of posts received prompted Green's publisher Penguin to seek a fan-designed cover for a reprint of one of Green's other books, An Abundance of Katherines. The Fault in Our Stars debuted at #1 on The New York Times Best Seller list for Children's Chapter Books and remained in that spot for seven consecutive weeks. A Hebrew edition of The Fault in Our Stars was published in Israel in August 2012 and more editions of the novel are forthcoming in Dutch, German, Spanish, French, Swedish, Danish, Icelandic, Chinese, Persian and Portuguese. The Fault in Our Stars has also gained places on several bestseller lists. It was #1 on The Wall Street Journal bestseller list, #1 on the Indiebound bestseller list, and #9 on The Bookseller bestseller list. The novel was also The New York Times Book Review Editor's Choice. As of January 2013, there are nearly 1 million copies of the novel in print. In December 2012, it was announced that a special edition with a silver cover and an expanded Q&A, dubbed the 'Exclusive Collector's Edition', would be available from Barnes and Noble. All or at least most of the copies first available for purchase of this edition of the book contained a printing error wherein several pages of the first chapter were replaced with pages from the Q&A section at the back of the book.
