Amazon denied Monday that “bulk purchases” were fueling sales of Ted Cruz’s new book, but the New York Times said it’s not budging in its decision to exclude the senator’s memoir from its bestseller list.

Amazon said in a statement that it has found “no evidence of unusual bulk purchase activity in our sales data” for Cruz’s recently released book “A Time for Truth.”

Amazon’s assertion, first reported by Politico, contradicted the Times, which said last week that the Texas senator’s book was left off its prestigious bestseller list due to “the overwhelming preponderance of evidence” that “sales were limited to strategic bulk purchases.”

HarperCollins, the publisher of Cruz’s book, has also denied that bulk purchases were driving the book’s sales figures.
