Nordstrom Rack $50 Groupon for only $25

For what its worth I bought to give to my wife and distract her on Black Friday and just printed it out. On the coupon, it explicitly says that it can be redeemed at any US location. This was a minor concern for me as it was available from a Florida group.

how long does it take to get a confirmation from Groupon? Never bought one of their deals before.
Deal is still good until midnight CST.

Thanks
