Right, isn't that because they are integrated? If you are buying from the google store that has all the info, makes sense. Were you buying from a microsoft store as well?

No. If I buy a package from Amazon and the tracking information goes to my gmail account, Google Now cards will automatically show my tracking numbers with links to view full tracking information.
What if you buy a package from Amazon and the tracking info goes to your outlook.com email? That'd be a fair comparison here. (maybe simply forwarding the email from Gmail to the outlook.com email associated with your Windows account would be sufficient?)
