As of May 14, USPS will have increased my cost of priority mail twice and other expenses have not gone down.

With this in mind, O2 clamps will be increased to $70 shipped to US addresses and $75 to non-US addresses on orders placed after May 13.

Autotune will remain the same price, but will no longer be convertible to WBO2 control(which I don't recommend anyway). That feature will be an additional $25 by special order only.

The for sale sticky will be edited to reflect these changes.
