Costing is much more than a simple "what do the parts cost us, how much do we pay the technician?". Factor in:
- Cost (to Canon) for warranty on the repair.
- Insurance (of your product) while on their premises.
- Return shipping charges.
- Packaging materials for return.
- Salary of person packing your gear for return.
- Overheads and general cost of maintaining a US repair facility (light, heat, premises insurance, telephone, stationary, etc).
- Local taxes for providing the facility.
- Training costs for technicians.
- Salary for technicians while training hence not earning money for the company.
- Employee insurance costs.
- Public liability insurance.
- Cost of holding the parts in stock at all.
- Cost of diagnostic machinery (whether or not it is used on your particular job it has to be available).
- Even the costs of booking the equipment into their facility / booking it out for return / raising an invoice / bank charges for processing your payment.
- Et cetera, et cetera, et cetera.
- Then there is the small matter of profit - no-one stays in business for very long if they do jobs at cost.
It always hurts when we get a bill for repairs. Always. If you're professional, it should be covered by your equipment insurance. If amateur, possibly
by your household all-risks insurance??
I too don't feel that you've been ripped off at all. Granted that others may get a more expensive repair done with more parts replaced for the same flat-rate charge. So may you one day (though I sincerely hope it won't be necessary)
. Conversely, someone may pay the same amount for simply having the zoom reflector adjusted with no parts used at all. It's the price we pay for having the facility for in-country repair - imagine what it'd be if everything had to go back to Japan for repair and imagine how long you'd be without your gear
