There's a good chance you never heard about Microsoft's very unpopular Grove music streaming service (Apple Music, Google Music, Pandora, Spotify, Deezer, etc.). 

Microsoft is determined to change the fate of this little-known offering by enticing you to subscribe with a fantastic deal: when you buy a single month of service for $US9.99, they give you two 3-month vouchers to share or use yourself. 

If you are a Microsoft fanboy already paying for this service, then you are out of luck, this applies to new subscribers only.

Here is the fine print:

This is unfortunatly a US only deal. 

You can subscribe here.
