I've seen their storage. The trick would be finding it in the first place! It's in a nondescript office building with no signage indicating he works there and the building has a security staff in place.
I suspect they're just prepping to refresh the product line - perhaps in anticipation of a new deck release!
They weren't selling much in the first place, if you recall. I never saw more than a few playing card items for sale at any time, and besides that he offered two caps, two t-shirts and about a half-dozen or more posters, but that was it.
