Thanks for letting us know. We've already got some alums on this to rescue it. I personally e-m'd the girl a polite note, asking why she is selling her badge. However, I'm not surprised that she didn't bother to reply. She is probably someone whose membership was terminated during college, and is no longer a DZ. Her badge should have been collected along with all other DZ memorabilia upon termination. Unfortunately, not all terminated sisters return their letters like they are suppose to do.
Fortunately, this is the first time I've seen someone selling their own DZ badge on E-Bay, so it does look like a rarity. Thank goodness!
