Anyone voting this down, ask yourself: why do I, as customer, care about your costs. That’s YOUR business, not mine. You tell me about your costs, my mind turns off and I don’t want to hear anything else you say.
Also, as a customer I do not mind thinking about a business' costs. In fact I want to know that a business is pricing a reasonable margin above costs and no more. I have way more respect for companies that don't see the need to mindlessly pad their profits. Not everyone is you.
(Not saying RS is being honest here but it is important to push back against this "pay no attention to what's going on behind the curtains" thinking)
