It was.
Unless FTGG LLC is not commonwealth that would be hard to believe.
You stated that only 1 person sold 1 pair of packers.
That's false:
http://www.ebay.com/sch/e-vil/m.html?_nkw=&_armrs=1&_from=&_ipg=25&LH_Complete=1&LH_Sold=1&rt=nc
This is the sold listing not the completed, so only listing that were sold not listing that ended by the seller or auction time ended will be show up.
As you can see the seller listed a 10 and 10.5 that's two pairs, both SOLD.
So either one employee got two pairs, to sell or your employees are using the same eBay account to sell shoes. Also this does not include the 3rd pair that was removed after this was discovered.
