For those that currently own the BF3 base game, what I did was buy the premium edition and then sell the base game on Ebay. You can sell the base game for ~ $10, maybe more. Mine sold for a little over $10.
Not sure if this would be any different from what Amazon offers, but Amazon gave you the 2 unlock codes, one for the base game and the other for the premium service.
