I sold Canuck57 a pair of Sennheiser HD 650's. Everything on his end was excellent. He communicated promptly and politely. He decided quickly and sent payment after shipping costs to Canada from the US were determined. However, the USPS messed up what would have been a flawless transaction by not holding up their end of the bargain with an unacceptable shipping delay. Thankfully, the headphones eventually got to their destination in one piece.
