No Doubt just tweeted to announce that they are taking part in an eBay auction to benefit Heal EB,a nonprofit organization dedicated to funding a cure while raising awareness for Epidermolysis Bullosa,a rare total body disease that causes blisters after the mildest trauma. Depending on the type of EB, the effects can be mild, disabling, or life threatening. The items included in the auction are copies of the Push And Shove, The Singles 1992-2003, Rock Steady, Return Of Saturn, and Tragic Kingdom CDs and an autographed poster from the band’s June 16, 2009 Toronto concert. The auction ends tomorrow at 9 AM PST-you can check it out here. Thanks as always to No Doubt for being so very charitable and generous.
