I was curious if there was a similar situation on Yahoo! auctions. So I searched Alpha Chi Omega, Zeta Tau Alpha, and Alpha Kappa Alpha (I believe these 3 GLOs have had issues with badges being sold on Ebay). Here are the results:

None of these include the sale of any badges. I think the most being sold are T-shirts and wooden-block cutouts of letters.
