What is the deal with the "Authenticators"? I had valid, name brand items purchased from the store with corresponding documentation returned to me that were returned with the reason: "Unable to Authenticate". And the response: "We can't share why because it will breach confidentiality." So, purchased from Neiman Marcus - authentication documentation - and still returned as "counterfeit". Hmmm....guess Ebay doesn't want my business for high end items anymore.
