Query: Do not buy from this vendor

While I would like to offer a useful review, I cannot due to the vendor's inability to satisfy the order.A friend purchased this hiking pole from our wedding registry. Two months later I received a call from Lee, who worked for the vendor, demanding additional money to have the item shipped. Shipping was paid in full during the initial transaction so I refused additional payment. Lee then informed me that the order would be canceled, but the seven dollars in shipping would not be returned to our friend that purchased the item for us.Amazon fixed the problem, but I would steer clear from buying anything from this vendor.
