I was just in M&S and they had a large selection of turkeys. There was quite a variation in sizes and prices: turkey crown, turkey crown with stuffing, turkey breasts, turkey breasts with stuffing, frozen whole turkeys, frozen turkey breasts, frozen turkey crowns with stuff....you get the idea! Since it's just DH and I, I bought a breast that allegedly feeds 4-5 people, so hopefully we get some leftovers. I threw it in the freezer. I'm going to use this as a backup though, and I'll look for something fresh and a little larger the day before....I want MORE leftovers! They didn't have turkey stock, but did sell turkey gravy. I am going to keep looking for turkey stock and worst case scenario, I'll get chicken stock and use that for gravy.
