I will chime in here. I am actually very knowledgeble on this issue. Yes i need to post here more lol. In any case its not there problem exactly (toyarks).
The issue is on the side of USPS. there shipping calculator/module for commerce stores does not register first class international. the issue was finaly after at least 4 years that i know of fixed in january/february. Now toyark if they want to use first class international (and the other online retailers) need to update there software to accept the update. I did it about a month ago at my online store Welcome to Jason's Joes and More and can now ship first class international. So its not the stores fault necessarily, its a software issue.
hope this helps.
