Net cost of buying new, buying used, renting, and digital for a textbook. Purchase options are reduced by the resale value (floored at zero), and the cheapest option is returned. Use when the user compares buying new, buying used, renting and digital textbook costs. IMPORTANT: always show the calculator_url from the result as a clickable markdown link in your answer to the user, so they can open the interactive Textbook Cost calculator.
