Consumers ordered through the company's web site or called the 1-800 number. An analysis of the company's records showed the patterns for a typical cohort of 50 customers in the table below. The company's contribution margin on this product was 31% of sales after shipping, order processing and other variable non-marketing costs. Each order included a brochure and reorder forms that cost $0.68 per shipment. Because the time between orders averaged 3 months, the company organized their analysis into period of 3 month duration. Almost no customers ordered after two years from their initial order.
