Film Title Query???????????????

Hello, could anyone please email me with the title of an 80's horror movie.
Someone must remember this one.
It was set in a supermarket/store, I remember one poor dude bought it in the
trash compactor, it just dragged his body right in, and another got it with
the meat slicer.
I'm sure the killer gets wasted by the cops at the end.
Hope someone can help.
Many thanks
