What is the most cost-effective method to ship comics via Canada Post to the USA with a Paypal-accepted proof delivery?
Size-wise, I am looking at shipping items in large document envelopes with cardboard protection. They are in the gray area where the value is too much for me to feel comfortable shipping without some protection from scammers, but not enough to spend $50+ on shipping.
I am having a very hard time definitively finding the answer on the Canada Post site, and the people at the post office seem not to know either. The answers I have found so far seem outrageously exhorbitant.
