The only reason I subscribe to Office is due to their OneDrive storage that is really helpful since I work with a lot of client data that I need to preserve at all costs. I have been renewing my Office subscription annually for the fifth year now. Except for one occasion, all renewal keys have been purchased through Amazon and always through Cloudtail/Cloudtail India. People are sceptical when it comes to purchasing digital items through Amazon. It's true that even I have had some rough experiences but so far they have handled it well for me. Overall, I am satisfied with my purchase.
