I am trying to ship pcbs internationally now and am using a small bubble mailer. For one board it is 1 ounce and for two it is 1.5 oz. I went to the post office and it was going to cost about 14 dollars to ship to sweden fom kansas city. What is the best way to ship these items and not cost so much I've only collected $4 for shipping on each of these. Your help would be appreciated. Thank you.
