I love these guys!  I've bought elsewhere, but since discovering them, I've never bought from anyone else.  They're friendly, willing to spend time with you (assuming it isn't a crowded day), and they're an endless fountain of knowledge about what's going on in the world of coins. My friends and I make frequent ""Karp Runs,"" to buy more coins whenever we have extra money to spend.	
	
I don't understand the guy who gave Karp a bad review. It so doesn't match my experience.
Pros:  Wonderful people, honest, great prices
Cons:  Can't think of any
