Horror Movies / DVD wanted

Ok So I am actually specifically looking for HORROR MOVIES. I checked out 'Mountain View Movies' since everyone seams to say they are pretty good BUT They dont have that HUGE of a selection (in Horror Movies). I have always seen stores on Ebay who specialize in a specific genre such as westerns or action and they have hundreds but Mountain View only has a handful of horror movies compared to the amounts I have seen on ebay stores such as 'Movie Magic USA'. Where else can I find Horror movies or how Can I contact other businesses about overstock deals? How does that process usually work?

By the way, I know the ebay market is flooded with DVD's and electronics but DVD's wont actually be my main product, just something on the side.

THANKS! -Matt

I would suggest you contact Mountainview specifically on this as they might be able to get you a much larger and more specific list.
