No course for ICORE, the IDPA course I teach, in Canada, will cost $20.00 and there isn't a course in the US (just like USPSA), I also instruct PPC and it's only $25.00, but it's all but dead in the east.
IDPA membership is $40.00/year, ICORE is, IIRC, $25.00/year and USPSA is $25.00, PPC? I don't know.
