I am in the US and am interested in an ebay auction from within Canada. Is it as simple as paying with Paypal and the person ships it just like if I buy it from within the US? Are there any extra "duties" I have to pay when it crosses through customs? How is Canadian mail handed over to US mail, I assume it would arrive to me by USPS? I just want to make sure I understand it all before I jump in and make a mistake. Thanks for your help!!
