Hmm, interesting. I bought the DLC myself not so long ago, like 2 weeks ago. Although I didn't purchase the game though PSN, I have a retail copy from Gamefly funny enough. It definitely is there, you can find it multiple ways. Start by clicking the store icon, then go to add-ons, then go to DISC BASED game add-ons, then A-L category, and it should be about 3 or 4 rows down once your in there, i'm looking at it as I type this. When you find it, I recommend you buy all 4, but in the 30 dollar bundle they have, otherwise if you buy them separately it will come to 40 dollars. Its called the Borderlands Extravasplosion Bundle, comes with all 4 packs, its extremely worth it my friend, believe me.
