I have Bioshock Infinite for the PS3 and I'm trying to complete the trophy list for that game.

I see that the game has 3 DLCs with trophies, if I buy the DLCs separately I will spend about 35€ I guess.

My question is, can I still buy the season pass for that game? How does the season pass works? If I buy it, will I get the DLCs with the trophies?
