OLD NAVY GROUPON: $20 for $10 is Back!

If you missed it last week, the Old Navy Groupon is back!  For $10 you get $20 to spend at Old Navy.  Make sure you read the fine print, because there are some quirks.  For example, you cannot combined with coupons and if you wait until after it "expires" it is only worth $10 (so at least you wouldn't lose money!).
