bf4 premium edition is the full game, along with all dlc battle packs and exclusive camos tags etc.

bf4 premium does not come with the full game, it's like an add-on with same perks as bf4 premium edition dlc tags camos except full game.

If you have the regular bf4 you can purchase premium, it will basically be like having premium edition.

Premium edition is cheaper because it come with full game and all exclusive content dlc tags camo etc.

If you are looking to buy premium you must already have the regular bf4.

regular game $ + premium $ is more money than premium edition $

if you are looking to buy bf4 get premium edition because it comes with everything basically.

I was confused also but found out when I bought premium. Hope it helped.
