Just a note on material mark-up, the burden costs for purchasing and stocking material, is a real cost, incured by a real business.
Example: 1/2" pipe may have a mark-up of 300% depending on how many times you have to move it, and anyone operating industrial or commercial operations should be aware of these costs.
Another issue, the customer knows what the material costs, yes he may, i know what a spark plug costs, but when i need my truck repaired, i would not question the service station on his mark-up, that is if i intend to have any work done there in the future, He has overhead and operating expenses to support, and so do you.
