Does anyone know a way to get multiples of specific cards from a tarot deck? I would like about 10 sets of just the major arcana. Actually, I need just 10 each of about 6 cards. I could print my own or maybe look for a deal and buy 10 complete decks, but I figured I would check first if anybody knew of a source that just sold the major arcana or singles. Did not find it on google or amazon.

I wonder if this helps

How picky are you about the design? I've often found liquidation/clearance sales of books where they also have table full of the same Tarot deck for 80-90% off original price.
You probably won't find your specific deck, but you might be able to stock up on 10-20 identical sets for the price of 2-3 decks. Use the doubles you need, mess around with the rest to make gaffs or something.

Find a bunch of like minded magicians ... and just buy them......
