Buying from E-Bay?

[irv]

Well, I got my feet wet and purchased a couple cards from E-Bay last night.
A 1959 Fleer Ted Williams and a 1961 Fleer Goose Goslin, both PSA graded.

Like what has been already mentioned, shipping rates vary exponentially!

Passed on a few I wanted more but the shipping rates/fees killed it for me, plus when I add up the CDN exchange rate, a $10.00 card can easily turn into a $40.00 or $50.00 dollar card!

Being since I was given a bunch of 52 Topps cards, I thought I'd give back or contribute to the hobby, but I am not sure, especially with what I mentioned above, if I can do this very often or not?

Any idea why shipping rates are so expensive compared to others? I assume the sellers also make money off of those?
I can understand, maybe, an expensive card, but when you see a $10.00-$20.00 dollar worth about half the shipping costs, it sure makes you wonder!

Edit: Can someone tell me why some cards/ads have an import fee/charge and others don't? I seen last night and today, some of those are just as much if not more than shipping costs.
