Microsoft trying to boost Surface RT sales is including for a limited time a free Touch: Touch Cover Limited Edition, or a Type Cover when you purchase the tablet (and you can choose from any of the variety of colors: cyan, red, magenta, white and black).
Starting Friday, May 31st, 2013 (and until June 30th), the promotional offer is available at the Microsoft Store, Best Buy, and Staples, and it is only for customers in the USA and Canada.
Although you are not getting a money discount here, you still getting a great deal knowing that the Touch Cover cost $100, the Type Cover is $119 and the Limited Edition cost $129 on their own. So you are basically paying $370, and that’s a pretty good deal.
Keep in mind that the offer covers both version of the Surface with Windows RT, 32GB and 64GB. If you only want one cover, make sure to choose correctly in the drop down menu, because you might just overpay your tablet.
