Problem:
Warby Parker is a retailer of eyeglasses, sunglasses, and contact lenses. Founded in 2010 as a completely online company, Warby Parker was able to manufacture its own eyewear and leverage its direct channel structure to sell prescription eyeglasses at $95, compared to the $200 or higher charged by major eyeglass retailers. Additionally, for each pair of eyeglasses that Warby Parker sells, the company donates a pair of eyeglasses to non-profit organizations that distribute the eyeglasses among the one billion people worldwide who otherwise lack access to eyeglasses. Based on this information, explain the various ways in which Warby Parker's holistic marketing approach enables its channel strategy, pricing, and corporate social responsibility (CSR) initiatives to support each other.
