I will echo this answer. Magic and Sports cards are more his speciality, but anything that could turn a profit is considered. Your best chance to speak with him is early in the day.
They do but it really depends on what you're selling. If you're just looking to offload an entire collection this is a good place for it and if you're looking to sell individual cards you're almost definitely looking at magic the gathering although he'll buy anything that he can make money off of. I found the owner to be very fair and honest when it comes to his dealings and this is a good place to go to.
