Ship to USA only?


I'm new to the site and have yet not made any transactions. I've noticed that most sellers on the classifieds are only willing to ship within the US. I live in Toronto, Canada and I'm simply wondering if there are reasons most sellers are not willing to sell across the border. Are there problems with Canadian customs?

I've bought and sold many items north of the border. And not had any problems. The key is this: I've always prepaid when I was purchasing something, and had them prepay me when they were purchasing from me. Some will argue this takes any control out of one party's hands, but I think a certain level of trust is already a necessity. I probably wouldn't do this with a high ticket item like an amp or something like that, but for cables etc. . . it's worked perfectly for me. Also, I think when a lot of folks mark 'usa only', they'd probably sell to Canada if you ask them to. Many don't think of Canada as 'foreign' territory.
I too am Canadian but have had good results doing cross-border business - selling & buying. Remember, never us UPS as they will add in $40 for brokerage fees. Fedex includes this in their prices. While I agree that it can be a little more paperwork for the US seller (usually just one extra form), I think its worth it if you can seal the deal quickly. At present there is no cross-border COD so there has to be a level of trust between both parties. To date, my purchases/sales have never exceeded $700 US so the risk has been minimal (although $700 US to the average bloke like me is still a few bucks and would hurt to be lost). With the now reduced cost of long distance phone charges a few calls between the interested parties would probably minimize the fears of a deal going sour. With the high exchange rate ($1 US = $1.5 $Cdn) us Canucks have to shop carefully but its my opinion that when we decide to make the purchase we are going to do so sincerely. Just my 2 cents worth....
Even on prepaid items, shipping UPS requires that the item be accompanied by several copies of an invoice. Then canada adds PST, GST and brokerage fees. My canadian buyer was really upset after paying an extra $90 (canadian?) to canada on a US$215 deal for a used Japanese unit. Like it was my fault. Then to top it all off, my bank later clipped me with a $3 fee for processing a canadian postal money order payable in US$. It's a shame but you friendly canadians are never going to see another piece of my equipment.
Add the following other reasons: PAYPAL doesn't serve Canada, in other words no good way to verify the transaction. Your legal remedies, if get's to that level, are extremely limited. After almost 30 transactions on the web, my only sour one was a Canadian. Not to say Canadians are untrustworthy, but are would surely like to do something to that guy who stuffed me!
