I have stupidly managed to buy a (clearly) fake Hermes bag from eBay. I paid using Paypal which at least had some payment protection. However, Paypal are asking me to confirm that the item purchased is not authentic: "This documentation should be from an unbiased third party, such as an appraiser or dealer. The third party should be someone who is qualified to appraise the item you received. The information should be on a letterhead that includes the name, address, and phone number of the appraiser so that we may contact them if we require additional information. We are unable to reimburse you for any costs associated with obtaining this documentation." Do you know who I can ask to do this? I'm not hugely keen on going to a Hermes store, but is this the only way?
