If the money were truly unlimited, that would make me think of cars, houses, swimming pools, furniture, etc.
So let's say I had an extra $1000, just for fun. There are quite a few out of print tarot decks I would like, and they can be fairly pricey. There are also some art decks that are signed, numbered editions that are beautiful. I have about 100 decks now, and some of them are limited editions. The artwork on different decks is amazing, and how else can you acquire 78 small pieces of art all at one time???
