Fallout 76 for Windows key is only $0.20 (yes, 20 cents) on Kinguin. I've bought a bunch of keys for stuff from them and never had a key problem and just bought the game and the key worked fine. It activates through the Xbox app for Windows. https://www.kinguin.net/category/133207/fallout-76-pc-cd-key https://www.youtube.com/watch?v=-FrhEF4_Hi0
