I sold shoes with StockX and shipped to them exactly as requested. I received an email saying they had not received information about the shoes being shipped and without any warning cancelled the sale. I sent shipping proof and they advised they would honour the sale. Once they received the shoes they shippend them back to me. No communication. I have now lost the $60 it cost to ship the shoes to them. They are now ignoring all my emails to their support email address. Never sell with StockX. They are an absolute joke.
