I do know that I saw them available online from one of the bigger retailers, but I have no idea if they're still in stock anymore. Aristocrats are great cards, and the "Seconds" program at USPC was pretty nice in terms of the cards you got - they usually played just fine and the imperfections were hard to spot, or so I've been told. I wouldn't be surprised if 2004 was close to if not the exact year that USPC stopped making Seconds - I never see newer decks and they're not exactly easy to find in the first place.
FYI: for all practical intents and purposes, USPC ceased production on the stock used to make Aristocrats and "Broadway Seconds". They eliminated Tally Ho stock first, switching that deck to Aristocrat stock, then Aristocrat stock was done with the Aristocrat 727 "Banknote" reprints from about two years ago. Beyond that, it hasn't been seen, at least not in anything outside of a casino deck. They may still be making it for casino customers, but for standard and custom decks, they're down to Bicycle Standard and Bee Casino pretty much exclusively, other than an occasional small run on some recycled papers they use for "environmentally friendlier" decks, which also have starch-based coatings and vegetable-based inks.
