DH's Comic Books collection - how can I find out how much they are worth?

Is there a site online or should he just go to a comic book store. I've never even seen a comic book store around.

There is a software you can buy. I'll have to ask DH the name of it. You plug in the information and it's condition and in the end it tells you how much it's worth. We had a friend who was abe to use his collection as a down payment for his house!!
