[Please read the update] We previously heard that Staples is offering $75 off when you buy any Windows Product, including Surface Pro and RT. Well now it seems that the software giant is doing something similar at the Microsoft Store online.

For a limited time the company is giving away a $100 voucher when you buy a Surface Pro 64 GB model (the only version in stock today). However, if the folks at Redmond deliver on the promise to restock the 128 GB model to the Microsoft Store and to Best Buy, you might just be able to wait until Saturday and get this model instead.

Now here is the catch, you cannot use the coupon when you make the purchase. You’ll have to wait until February 19th to receive it, but because chances are you’ll want to buy a Touch or Type Cover. You could order a Surface and then in a different purchase after the 19th, you can buy the cover you want and use the voucher.

According to an statement at WinBeta, the company said:

As you can read in the statement, you will also get the 100 bucks coupon, if you buy a new Windows PC (including a Surface), that is, of course, when the value is more than $699. Also note that you cannot use this offer to buy another Surface.

“Microsoft is currently running an online promotion on www.microsoftstore.com which is valid until 2/18/2013: Buy a PC over $699 and get a $100 discount code coupon for future online purchases. The $100 discount code coupon must be redeemed online at www.microsoftstoreonline.com between 2/19/2013 and 3/17/2013. The $100 discount code coupon excludes Surface RT and Surface Pro tablets, is not valid on prior orders or purchases, cannot be transferred or otherwise redeemed for cash or gift cards and cannot be combined with other offers. The discount coupon code is limited to 1 discount per PC purchased,”

Update: Apparently it might has been a glitch and this offer does not longer apply for the purchase of Surface, even though is over $699. However you can still get the $100 coupon, if you buy one of the qualifying Windows PC that Microsoft is offering at the online Store and the value is more than $699.

Update: New details on the Microsoft $100 coupon promotion.
