I want to buy office 2021 pro plus. But my financial condition isn't so good and right now I can't afford the price Microsoft official store are offering. So I try to search for cheap office 2021 pro plus. Then I found the website called MSCDKEYS. Then I visit it and explore that. It seems legit and also they have Microsoft's official partner id. So here I'm confused. Is it really legit? Can I buy from them? Thank You.
