For roast beef or chicken it is too easy to make your own from fresh meat.
The roast I will bake for a couple of hours then chill in the fridge.
After that I can cut slices of cold cuts off it for sandwiches or for soups.
The chicken I can bake, then eat the dark meat right away, and save the breasts for cold cuts later or for soups.
The only thing I ever buy packaged is corned beef, which I boil until done, then chill and slice later for cold cuts.
