I purchased Birkenstock shoes from a company I was not familiar with which is risky but I used PayPal because of their buyer protection program. The shoes arrived and they are very cheap imitations. I filed a dispute with PayPal. They said I had to return shoes to seller for refund. Shipping to return shoes was 57.00. Almost as much as I paid for them. PayPal will not budge. I guess they care more about the Chinese fraudulent seller than their customers.
