I’m buying a Steam Deck OLED for my husband and it seems to force me to log in to buy it. Would it be of any benefit to my husband’s account if I use his login? Are there points he could use from my purchase to use towards a game? He doesn’t check his emails ever, so I don’t think it would ruin the surprise.
You get points from purchasing it, but they can’t be used to buy games. They’re just cosmetic, you can buy avatars, backgrounds, avatar frames, emoticons, etc. Anything in the points shop.
You can also claim a profile bundle, and if you get the 1TB there’s also an exclusive startup movie and keyboard theme. Make sure when you get the Steam Deck you log into the account you want to claim those on as you can only claim them once. (You claim it when you have the Steam Deck in your hands, it shouldn’t matter which account purchases it).
