The BattleCorps BattleShop continues to work fine for PDFs, but there have been multiple cases of individuals posting to this board complaining they have ordered physical products and not received them, and being unable to get a response via e-mail channels. Explanations for the problem include a software error that buried physical orders in the system for a period of several months, and incompatibilities with the third-party fulfillment warehouse's system, which had a tendency to mark physical/PDF bundle orders as delivered when only the PDF had been downloaded.
The above is all based on my reading of forum chatter, and not from the horse's mouth or based on personal experience. I personally have not had any problems with PDF orders or purely physical orders, but have admittedly never bought a PDF/book bundle.
