I just purchased a Microsoft Office 2013 Home and Student (download delivery,) followed simple instructions with the product key. When everyhting was done, I went to the Word Document application on my desktop on my laptop and a popup appeared to validate my purchase and it had told me that I had already used the product key multiple times when I only typed the product key once. DON'T BUY ANYTHING FROM THIS WEBSITE BECAUSE IT'S A SCAM! Money wasted to this website.
