I will add my thoughts here and what i encountered regarding shipping
International shipping is the only barrier between me and my wish list

I understand the cost for post services to handle items for us from one side of the planet to another, but some courier services are way tooooo expensive delivering the same service for the same delivery time.
I have always used USPS Priority Mail International for my purchases whether from Steve or anyone from the swap here and always pay approx $30.00 - $40.00 depending on size and weight of course.
I only once paid over $50.00 for a tube but it contained 2 kites, with lines and Rev handles..the tube empty itself weight more than the kites only lol (but this was a truck proof tube and thanks to the shipper for this)
He advised me about the cost and we shared in half.
As long as the buyer will pay for shipping, sellers should not be worried about anything than the item shipped itself (the most important thing anyway)
Now comes customs values, declare and insurance values. Customs will charge you based on the declared value on the form filled by the shipper. They don't know what is a Blue Moon kite or a Benson DS..so $30.00 for a kite for them is like normal thing/price. This can help some buyers where customs are harsh on taxes, etc
Personally my customs are a bit harsh for items getting over $70.00 and then they begin asking for invoice, import permits, country of origin, etc..that is why i always ask my shipper to declare a lower value to avoid these issues here.
Till now (and i touch wood as i write) I never lost something or received only partial package and insurance did not have to get in it. But the risk in this process is the day where something gets lost and the procedures are more a PITA than the item lost. But anyway, the package is sealed when it arrives in my country and is opened in my presence with a custom officer.
Somehow, i am like a prisoner on my island and i will always know these procedures for shipping and thanks to all those who helped me get my kites and accessories safe.
