Does this work with the 1600 points offers? If so then it's an awesome deal IMO.
*Valid for $25 off of a transaction of $75 or more. Voucher expires on April 8, 2013. Redeemable only at participating Microsoft store locations (not valid in Canada). Excludes Surface and Surface accessories. Not valid on prior orders or purchases; cannot be transferred or otherwise redeemed for cash or gift cards. Not combinable with other offers. Limit 1 voucher, per participant, per transaction, single use only. No reproductions of voucher will be accepted. While supplies last.
The prior orders language may exclude the coupons use, but in my experience in store they don't really care, they never allowed multi coupons in a single order, but I did multi transactions using different coupons in the same store visit.
