Dear Billy,
(1) Valid Contax Club Member Card holder can have a 20% off for repairing for any case.
(2) The min. charge is $150 if the camera was sent to Japan for check. And UOI will take care of those delivery cost.
(3) You can make a call to UOI the repairing centre manager first to see whether there're still part in Japan.
You can refer the detail from the page in our old website

Remember to bring your Member Card if visit UOI
BTW, the repairing information will be moved to this new forum later
