if I own a book irl How do I add the book to my account

They could do it like textbooks do with online content and make each code unique and one-time use.

Good one to use if fight club 5th edition 

You don't even need packaging, just make the code only be on the receipt. so you can still look at what exactly you are buying in the stores but get the digital version only when you bought the physical copy

 This has been addressed before, but the short version is this requires infrastructure that a lot of smaller gaming stores cannot financially justify. This in turn puts them at a disadvantage compared to big box stores.

 The guy who runs the friendly local TTRPG/Game store in my town still uses one of those old addition calculators the goes "chk nk chk nk chk nk" every time he adds something on there, and prints out this tiny little 1985's looking receipt. There isn't going to be any code on the receipt.

A system like this only punishes small, local stores because people will want that extra code and so will instead shop online or at big box stores. 

No thanks. 

This isn't a dishonorable business model, in fact it is quite the opposite.  I have many physical books, many of those I also have a digital copy of.  

However, there are some products that I have no interest in the physical book so I purchase the digital product and save a bit of money.

A completely remote player might have NO interest in the physical books, or younger players who are more comfortable using technology than dusty tomes.

Why make customers pay for products they don't need and won't use?  Some groups are strictly printed materials around a table after all.

Unfortunately you don’t, and that’s why Wizards aren’t as good as Chaosium or C7 or people like that who give you a pdf copy when you buy the physical edition from them. WOTC have had the last of my money, bollocks to them! I’m afraid it’s pencil and paper old-style unless you want to carry on paying through the nose for stuff you already paid for. 

WOTC, give folk a disc with a character generator like you did with 3.0. - Even if you never actually carry through on your Mastertools promises and give us a finished product. . 

I have never met one of these people who have “NO” interest in a physical book. “Dusty tomes”?  Presumably they have an easier time of reading two column portrait orientated  pdfs on a landscape screen than I do.

 Ignoring questions of personal taste and reading devices (tablets work pretty well for it IMO), there's a substantial number of people for whom a physical book has negative value over digital. Books take up space. They have to move when you do. Even if you have a home with space, and you're not moving any time soon, if the game isn't where you are, you have to carry them there. If you have bad eyes, there's not much you can do with a physical book to make it more readable. (And what if you need a screen reader?)

I personally prefer physical books for reference works (which most RPG books are), but, having recently moved, it really reinforced what a pain physical books can be. (And DDB books are way easier to use as a reference work than a PDF is.)

I'll confirm that I have far more digitally than I do physical. Most of my D&D play is online and the Beyond toolset is a part of that, and I like having access on all my devices the way I do. I haven't bought a physical book in a few years, though I have 10 total. These include the legacy Mordenkainen's Tome of Foes and Volo's Guide to Monsters.

I used to have a bunch of 5th Edition books, but I ended up getting quite a few digital for ease (the 'big three'). I have since moved completely to Digital because I find it easier as a player and a DM to reference from the digital tools. The physical books simply didn't get used and were gathering dust, so I sold them all very recently.

I miss reading through them, but I haven't gone back since going full digital.

Should clarify if it wasn't obvious, this isn't a pile-on for digital being better than physical - everyone has their own preferences and there is no 'correct' way to have books.

I absolutely hate that I cannot get the most basic rules from the players handbook that I own as a standard set on this tool.  Pathfinder forever.

Great job being vague enough that nobody can actually tell what you're talking about.

 You can, they're funnily enough called the Basic Rules.
