> spending patterns in developing countries, where cigarettes are sold in singles and shampoo can come in tiny, pricey sachets. I wouldn't call the sachets pricey. They are single-use and come at an extremely affordable price (mostly just one rupee = 2 cents). Sachets allow the poor to try out products that they could not afford before, or products that they don't use daily. Sachet sales created a whole new business paradigm.[0] They form the basis of C.K. Prahalad and Allen Hammond's article Serving the World’s Poor, Profitably (HBR September 2002) [1] and C. K. Prahalad's book The Fortune at the Bottom of the Pyramid (Wharton School Publishing, 2004).
