Far Harbor Deals
Far Harbor is the most expensive piece of Fallout 4 DLC.
Automatron was $10, Wasteland Workshop was $5. Far Harbor is going to cost you $25 without a deal. That's half the price of Fallout 4 (retails for $60 most places).
Unfortunately, we probably won't see a ton of deals on the Far Harbor DLC. Green Man Gaming is offering a 20% promo code but it's limited to the PC version of the game.
DLGamer is also taking 11% off the price dropping it from $25 to $22.24. Not as good as Green Man Gaming but a deal nonetheless.
Deals on Fallout 4 DLC for Xbox One and PS4 have been scarce and there probably won't be a ton of offers on Far Harbor. At least for awhile.
Keep an eye out as we move away from the Far Harbor release date.
