Excellent tickets...just released

This was the headline for a full page ad in my Washington Post "Arts" section this past Sunday. You see, Madonna was in town for two shows, Sunday and Monday - her "Reinvention Tour". I had decided I didn't want to go when the tickets first went on sale about two months ago, and they quickly "sold out" both shows. So my question is where did these "excellent tickets for both shows just released" come from? By the way, she got a great review for the show and I now wish I had gotten tickets. Oh well, going to see Sting and Annie Lennox(together) later this summer.
