The downloadable PC version of Borderlands 2 is bundled together with the game's Season Pass for only $25 today only at Amazon. The Season Pass typically sells for $30 by itself while the game has been going for $30 to $40 since the start of 2013.
The Borderlands 2 Season Pass comes with four DLC packs - Captain Scarlett and Her Pirate's Booty, Mr. Torgue's Campaign of Carnage, Sir Hammerlock's Big Game Hunt and a fourth unannounced DLC due out this summer. Gearbox Software recently added the Ultimate Vault Hunter Upgrade Pack to the Season Pass which raises the level cap to 61 and adds the Ultimate Vault Hunter Mode which offers a more challenging second run through of the shooter after the game is beat and players level up their character to at least level 50.
