Well, not having either store handy, I have only anecdotal evidence - I have very clearly been told by others that Walmart and K-Mart do carry D&D products. Never heard of third parties getting sold, but D&D itself does get on their shelves.
The question, then isn't why the products aren't there (because they are). The problem is why they aren't more visible.
