Johnny's right, shipping makes a huge difference. So does the the $90 include shipping costs?
As an example, I purchased a part from a fellow in Canada. He shipped it to me via FedEx for ~$20. Ends up the part was bad so I returned it. Well, ~$50 later in shipping costs despite the same locations on either end, the same box, the same item, the same weight and the same shipping company, I swore to never buy from Canada again if there was even a remote possibility of having to return it.
I don't *know* why this is the case but it seems to me it likely is the Canadian government requiring all the extra customs and brokers crap to ship from here in the US to there that increases the shipping costs so dramatically. NAFTA, my a$$.
edit: Well, I stand corrected then if it's the shipping companies adding the extra costs, I just wonder then why only in the US to Canada direction are these fees added?
