The move comes not long after an increase in price for D&D books across the board. Physical copies run $59.95 normally, and the digital + physical bundles are $10 more, putting them around the same price as most newly released video games. The digital + physical bundles work exclusively with D&D Beyond. Meaning other platforms like Roll20 and Fantasy Grounds have their own separate content they do not sell bundled together.
But they aren't giving you the pdf with it either. They're giving you access to a digitized book that they can cut off access to whenever they want to push the next edition. It's just another example of Hasbro missing the entire point of the community's complaint.
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.
I don't think the prices increased for the core book bundle or the PHB/DMG but I haven't kept a close eye on those.
It's also worth noting that this shop is run via scalefast and I had some issues when I did the dragonlance preorder of getting my product on time due to scalefast.
I'm winding down this two-year campaign I've been running and then ditching 5e for some other system. I made that decision back when the whole OGL shitstorm happened. I just don't trust them to not screw around with things anymore, and, anyway, every time they come out with another UA for One D&D, I read it and get pissed off again.
So they can bundle deez nuts. I'm moving to (probably) FATE or Blades in the Dark.
