Best Pre-Ground Coffee

Hey, so I know everybody's going to hate this, but I want to buy some pre-ground supermarket coffee that has as deep and rich a flavor as you can get given those restrictions. I go for quality foods in most areas, I'm just not that much of a coffee person, so I don't really intend on investing in a grinder, a french press, an espresso set-up, anything like that. Just got an old percolator and want to get some coffee to use with it.

So, what I'm looking for is a deep taste without being too bitter, something that goes well with breakfast meats, or like beef-and-beans type meals. So like, doesn't have to be smooth and like none of that latte stuff, something as dark as it could be without getting too acidic (yeah I know fresh-ground would be better for all that). The picture on that brand with the picture of the guy and his mule (Juan Valdez?) leads me to believe that that is the kind of coffee I want, but I know looks can be deceiving. Is there anything ya'll recommend?
