While the site has much room for improvement, overall it's a good source of authentic designer items at great prices. When I received a fraudulent item, their customer service response was satisfactory in that they worked to resolve my issue, albeit slowly, and provided a full refund after confirming the item was indeed counterfeit even though their authentication service incorrectly authenticated the item.
Dear Evette, thank you very much for taking the time to share with us your feedback on your experience!
