Ha, my kid takes my advice.
He sent a list of desired text books last week and this afternoon we ordered five of them. He said only to get "a couple," but he'd prioritized them so it was easy to know which to go for first. Some of them supposedly are available on Kindle, but I'm skeptical that they would read correctly on Kindle. I've heard math often does not display properly.
