Like I said, we're not retailers. If customer X goes into Home Depot and finds a part I sold him for $20, and finds the exact same part for $12, I have just lost a customer.
If you happen to get a great deal on a bulk buy, sure, go ahead and mark each item of that package up to the retail price - nothing wrong with that. I usually do that with wire when I sell it by the foot off of my reel.
However, customer X is going to think that "electricians are rip-offs", and who needs that kind of publicity to make an extra $2 on a bundle of 1/2" EMT? Our product is our skill and knowledge, and that is something he can't get at a big box store.
BTW, I'm just relating how I do things and my view on it. I make no judgments on others. If you think that bumping products up 40% is a good business choice, and your customers don't seem to mind, then good for you! We're all in the business of making a living.
Good Luck!
