Nightmare selling to Canada

I didn't see 'site-related' as a choice so I'm using 'misc audio'.I feel bad for Canadians wanting to buy our gear. The weight limitation---66lbs--fedex or the PO--- Then unless you lie on the form they may have to pay huge fees.--(up to 35%)????I had a deal in progress; the buyer sent a Canadian MO.I took the bank check to the operations manager at my bank.--She tells me there could be a charge back to my account for a period of up tp 45days later.---I sent the bank check back; unless the buyer wanted to wait 45 days, before I ship the item.As I was returning this check--the postal lady says I could get cash for a Canadian Postal Money Order. --I'm surprised the buyer didn't know this.---After the fact; I now know this.---Sad but true
