In the old days, they used to cook a whole turkey, then carve it up and sell both the white meat and dark meat sliced in the deli. These days, it's mostly the highly processed stuff (white only) and occasionally you can find a place claiming to have unprocessed turkey. (It's never off a whole turkey though).
Is there anyplace still around that sells real dark meat turkey, sliced? In an informal poll of friends & co-workers I've found that about 30% of folks actually prefer the dark meat! So if there is a place, they should sell a lot of it!
