The shipping rates on the A Terre bigcartel page have been adjusted to reflect the changes by the USPS. This means that it now costs $9.45 to ship a single cassette overseas. I wont be instating a minimum order policy, but bundling orders / ordering more than one tape is highly encouraged. Before the next batch is released, I'll try and send a healthy amount to a European distro.
There are three new cassettes slated for release sometime in February or early March. Possibly a fourth if the new El-Ahrairah gets written in time. Updates in the coming weeks.
