Assassin's Creed Series

Alright, if you look at some of the earlier Assassin's Creed games on Amazon, they have some pretty good deals. The only problem is, there are only good deals if you order the physical copy, rather than buying Steam code. I know that some games will come with a code even when you order a physical copy. Does anyone know if that's true about these ones? If it comes with anything, I assume it will come with a UPlay code, rather than a Steam code, but that's better than nothing.
