The product you buy is not the product you sell
Question: If you buy a product at cost or wholesale price from a manufacturer or wholesaler, what percentage should you put on it before you sell it at retail?
Answer: The definition of business I find most useful is this:
“Business is the exchange of resources for mutual perceived benefit.”
In other words, by definition it has to be Win-Win to work.
For the buyer, it’s an EXPERIENCE — not just the BENEFITS they enjoy, but how they FEEL about those benefits (or absence of benefit). THAT’s what drives them onto Social Networks, Review sites, friends’ phones, etc, to either rave about you and your product/service, or to rant about you.
