So now he's dictating to you the seller how to ship and how much he's going to pay. That doesn't fly, this is your auction. In future listings, I would lose the above quoted sentence. List s/h prices for Priority AND Parcel Post (for example). Folks can choose which one they want. Tell int'l bidders (within your auction listing somewhere) to contact you BEFORE bidding for a shipping quote (unless you know for sure what you will have to pay to mail it to said country).
Everyone deals with a nutty buyer now & then and there's always going to be that negative FB from someone who doesn't understand how things work. To me, $8 sounds dirt cheap going from WI to Canada, no matter what the item. Stand firm, if you let him bully you you WILL regret it.
I wouldn't even worry at this point about him emailing other bidders, it's too early for that, but that's a reportable offense to be dealt with if and when the time comes.
Has he paid yet? You've comitted to $8, send him another invoice and just leave it be...do not communicate any further unless it's something pertinant. If he still tries to negotiate shipping, ignore him.
