Nuka World Deals
If you don't want to pay the full $20 for Nuka World, you don't have to, assuming you're playing Fallout 4 on a PC.
Green Man Gaming is taking Nuka World orders and you can save save 11% off the price right now. A small difference but a deal nonetheless.
We've seen PC deals emerge for the rest of the Fallout 4 DLC so there's no doubt we'll see some other Nuka World deals emerge.
Just don't expect many (or frankly any) for the Xbox One and PS4. Fallout 4 DLC deals for console are still extremely scarce.
