If you are an international customer trying to place an order and are noticing that priority mail (a more expensive option) is the only one available, we are working on the issue! The post office initiated a rate hike earlier this month that seems to have caused the issue.
We are working with the web designers to fix the issue. If you place an order, the postage will be adjusted to the correct amount for 1st class postage (up to 4lbs).
