Needed another license for Office 2010. Not exactly cutting edge S/W but I hate having to use a totally different GUI every time I switch computers! The price was reasonable and the download key arrived about an hour after I placed the order. The key I received worked both to allow the initial download and for product activation.
The key I received DID NOT work with my existing Office Home and Student three license CD. But then, my download was actually an upgrade to Office Pro, which is a more complete product. So I'm not complaining.
