Yep, TFCC only goes by USPS Priority Mail International, as opposed to using USPS First Class International which is around $16-20. Priority has better sender assurance because its tracked and confirmed, and gets here 6-10 business days, however I have never had an issue with First Class, which has always arrived within 10 business days as well.
The Terradive mould makes for great Cyberjets, but not Depthcharge. Depthcharge really needs more beef, and that upper body frame just does not work out. Can you imagine that little guy going up against BW Rampage! ;)
