Will You ship outside of the US

i'm a regular seller on ebay, and occasionally here on this site also.
i sell worldwide from finland, to australia, and everywhere in between.
i can understand why people don't like to send stuff out of the country.
when i have to look up what it costs to send parts up into canada, and around the world, a great majority of the time i never hear back from the people that i gave the quote to in the first place. So why even attempt to do it.
it is super expensive to send parts out of the country in this day and age, and people are thinking that you are ripping them off with the shipping quote that you gave them.
so why even bother taking your time in in figuring out how much the package weighs in at, figuring out the shipping, to wherever it's going to, and if boxes, and packaging materials have to be figured into the quote, it's not worth it for lots of individuals to do it, when everything is factored into the deal.
then if you estimated incorrectly, when you get to the post office counter, are you going to eat the difference, and loose, and send it out anyway?
well you asked, i replied, just my two cents on the subject.
this is 100% true and i have lost sales becaus of the facts stated..
