I consider myself an informed shopper, and I have never heard of this practice before! I have shopped many, many GOB sales and I have not noticed any suspicious merch. I do, however, tend to shop the last days of GOB sales, and I pay close attention to the markdown schedules. I shopped Filene's GOB sale just yesterday and got some great deals (edited) but I am definitely planning on going back for the final day. This definitely makes me think...am I getting a deal on Filene's merch...or a "deal" from a liquidator...
