GS Arctic Cables Custom Pure Silver Palladium 2M TH900mkII to XLR

What the difference between Garage Sale (GS) and normal items listed on www.mimic-audio.com? 

These are items taken in trade, or used for demos, or are opened returns, or dead stock in 9/10 or better condition(unless otherwise noted)! This is the first annual Garage Sale that aims to lighten the shelves in preparation for refilling with new, updated items in the coming year!
