"The average student here at Purdue and other places are spending $1,200 or more a year on that now," he said. "It's the third-highest cost of college."
Daniels hopes a new co-branded Purdue Student Store on Amazon will help students save up to 30 percent, or $6 million a year, on textbooks.
On the issue of paying student athletes, the Purdue University president said, "There are lot of unintended consequences that could come to a system that is already suffering with wretched excess in money and overemphasis on sports."
On Friday, a federal judge ruled the NCAA cannot stop players from selling the rights to their names, images and likenesses. It struck down NCAA regulations that prohibit student-athletes from getting anything other than scholarships and the cost of admission.
The judge did say the NCAA could set a cap on the money paid to athletes, as long as it allows at least $5,000 per athlete per year of competition.
The NCAA said Monday it wants clarification on two points contained in the ruling—asking the judge which recruits are covered and when it starts. The college governing body plans to appeal at least part of the ruling.

"I think this is [a] very troublesome development if it comes. I would point out there's an enormous value provided to student- athletes, the value of a scholarship and all the things that go with it—well up into six figures already," said Daniels—adding Purdue's student-athletes on average perform better academically than the student body at large. "And our athletic department pays for itself. We don't ask other students to subsidize it."
