I have been sticking to the same every year; Raimi, Romero, Carpenter...any of the recent remakes I didn't hate.
But this year because of my budget (and tastes coincidentally) I'll be digging into the old, crusty, forgotten ones. I picked up a double feature with Carnival of Souls and Horror hotel. I also have The Last Man on Earth with The Last Woman on Earth.
Fortunately there's a plethora of bundled horror "classics" readily available. Has anyone bought the 4 Film Favorites of Dracula? That's one I might be getting for a good price.
