I was amazed when I saw the prices at which Buy MS Office were offering Office 2016 products. I ordered one which I could afford, paid by credit card, received an acknowledgement within a couple of minutes. Later that day I received a phonecall to verify my identity and my purchase, and within a few minutes received an email informing me that they would upgrade my purchase to a better product at no extra cost, with the product key, which worked perfectly. By the time I went to be everything was up and running. No complaints whatsoever.
