I learned my lesson on dimmers and fan controls. In the past I charged a bit more than my suppliers cost me. Sell and start the job. Were short one so I jump in the truck to go to the big stores. The box store charges more than I charged the customer. So I loose money and time. Then they call the next day cause the knob broke off. So I waist 2 hours and gas picking up another one, driving, replacing, and returning the bad one. Then there is the chance of someone fring one out. I think we all have? I had a 1000w 3 way this year go up in smoke. Had another one a guy broke tring to cram it in the box. I also ate a low voltage dimmer cause they gave us a magnetic instead of a electronic one. Was installed no returns. That is a few hunderd in losses on these things. I need to charge a reasonable amount to pay for warrenty, over head, bad debts, and MAKE A PPROFFIT. Charging only a few dollers MU on these items I would loose money.
