[Question] Were can i find a list of Safe Sites where buy Steam Games/Keys/Bundles??

As pc gamer (and new Deck owner) i've started to check any good game deal, mostly x games on Steam but not only. I've soon realize that there are great site like Humble to use to buy keys for cheap, but also "shady" sites with very low price who apparently sell non working keys or try to scam you. Did we have a list of the "Safest" site where buy games???
