TL;DR - At the website dndstore (dot) wizards (dot) com, you can no longer buy JUST the physical books. You must buy the bundled Physical + Digital copies for 59.95 USD. This makes a decent amount of sense from a business perspective, as WotC is all-in on a digital gaming world with D&D Beyond and all that. Physical copies of the book are (as of right now) still available on, say, Amazon for ~28 USD.
