I'm aware some of the cards create situations where you made need more extra pieces (more than the single extra queen included with most chess sets). However, I run a middle school chess club and we have many sets and plenty of extra pieces for the inevitable breakage (you'd be surprised how often this happens with 12 year olds). If there was a way to purchase just the deck of cards and not the board, I would have certainly bought a case for my club. I spoke with two representatives at PAXU about this and they told me there would be options for bulk purchase, but I simply can't justify all those extra boards and piece sets. If you retail or do further campaigns I would strongly recommend a card only option for customers like me. As it stands, I bought one for myself and will probably bring it for my students to try, but I think you all missed an opportunity here.
