I find it hard to resist buying them, myself - because every new deck tells different stories, in a different way...and if the art is truly beautiful to my eyes, all my resolve melts, and I HAVE to have it! Specially if it is OOP and doesn't come up too often. I just did a big deck splurge, myself...!
going to have to stop now, though. To be fair I had only bought I think 3 other decks this year, so really, it's not too too bad.
I guess it's a different thing for every person. Some people can't resist buying shoes, some can't resist new electronic toys, etc. and my addiction seems to be decks and crystals. Just can't stop myself!
ETA: A few months ago, I spotted an OOP deck kit I really, really wanted...it was at a super good price...I hesitated, trying to be fiscally responsible...when I went back to the online store to get the deck, finally, it was gone
Now I have the deck, I managed to trade for what I wanted, but it didn't come with the book. So I wish I had caved the first time, when I saw the whole package! Strike while the iron is hot, they say!
