Groupon: $25 for $50 Worth of Apparel at Gap

Today's Deal at Groupon: $25 for $50 Worth of Apparel at Gap.

Expires Nov 19, 2010
Limit 1/person. Valid in-store at US and Canada Gap stores only. Not valid @ Gap Outlet, Factory, Generation, online. Not valid for GiftCards, tax, or w/other offers. $50 minimum purchase.
Can not be combined with other discounts or rewards.

 This is a great deal if you shop at Gap.  I do wish it had a later expiration date (oh, maybe Black Friday).  Not sure if it can be used at Old Navy or Banana Republic. If anyone finds the answer to that one, please share!
