Every so often an online auction is too good to miss. Take, for instance, Jack White's "Garage Sale" August 26th through the 30th. Signed guitars, amps, stage equipment, notes - it's all coming out of Third Man Records, the record label Jack White started in Detroit, Michigan, and every piece of memorabilia comes with a Certificate of Authenticity. And don't feel guilty about dropping some coin. Some of the proceeds of this online auction will stay right here in the Mitten and benefit will benefit the Detroit Phoenix Center whose mission it is to provide "services that empowers youth with the  resources and support they need to build community connections, increase self esteem, and actualize their dreams." So go ahead, treat yourself to the newest part of your collection, like a crash cymbal used by White Stripes drummer Meg White or a Third Man Studios Mackie Mixing Console, and know you're helping Michigan youth.
