Non-Microsoft employees are able to purchase logo merchandise on the Microsoft Company Store website:
When you arrive at the homepage, you’ll see both a couple of boxes: a New Customer area to the left and an Existing Customer login box to the right. If you look at the New Customer area, click on the "Non-Microsoft" option, you’ll be able to set up a new account and shop for promotional merchandise. In fact, you’ll see all the same items available to Microsoft employees except for hardware and software!
