I don't know about not listing prices (that seems shady), but surely you realize that the cost of the ingredients have very little bearing on the final price of the product? Unless you assume that running a 7-11 or any other store or restaurant that might sell food has zero overhead, with no rent, utilities, taxes, or employees to pay. In a further note, profit has got to be one of the most misunderstood things in economics. Every endeavor of human commerce has to involve profit for at least one party, otherwise the transaction would not occur at all. If you can put together a sandwich for $1 in ingredients and, say, $4 in your time and labor, why would you sell it for less than $5 plus some profit? At exactly $5 you may as well not engage in this business at all, since you've effectively gained nothing.
