I'm planning out my holiday shopping and noticed the Physical Gift Set bundles also provide digital copies of their respective books. How quickly do you get those digital copies from the gift sets?

My plan is to get the two physical bundles when the sale drops, hopefully have the digital copies available on my account immediately, then purchase the Source Bundle for the missing digital copies on D&D Beyond. However, since the physical bundles are via WotC's main website, I don't know if it's a physical code that gives the digital books, which means I'll need to wait for it to arrive, which may be after the sale is over.

I bought the physical/digital bundle for Shadow of the Dragon Queen through WOTC and my invoice had the link to the product key that i could enter on DNDBeyond. That was within a few minutes.

I can’t tell with the other products but i don’t see reason why that would be different.

My other question would be, dnd beyond discounts bundles based on how much you've spent on the included books, not how much they're worth.  So I'd be interested to see what discount you'd get off of the source bundle after purchasing the physical bundles.
