In 2019, the release of Donald Trump, Jr.'s book "Triggered" was shown to have only reached the best-seller list through approximately $100,000 in behind-the-scenes bulk purchases meant to pump up its sales numbers illegitimately. "Vanity Fair" reported in October 2020 that this sort of gaming of the system has been a common practice among American conservative political figures, and has also included the use of political campaign funds to purchase the books in bulk in order to boost their rank on the list.
