Sounds like a good idea in theory, but I wonder how many people who buy the codes are willing to go out of their way to trade them in a for a floppy in the first place? I can't imagine it being a large percentage
It's not a huge percentage, but it's an option that allows publishers to keep releasing digital, while having an option for stores to make money from existing customers. The option is the point.
I get both of these things. My LCS uses ComicHub, I'm quite familiar with it, and id happily order digital copies through there and pick up floppies when COVID blows over. My point is just, the "game-breaking" announcement is just that ComicHub has the capability to track this stuff, not that anyone has actually agreed to it. Having software that can do it versus having publishers like Marvel and DC actually agree to giving away two copies of an item for one purchase is a different story.
The general hope I'm reading between the lines is since Marvel and DC already gives previews to ComicHub, that the company has more leverage to convince them this plan will work, without a disruption to weekly publishing.
My guess is still that the Big Two will jack up the price for these digital/physical bundle issues to cover costs. Theoretically, since it's digital first, then physical, then takes care of one of the bigger problems, that folks would buy physical and give the digital code away.
