CASE STUDY – I
Rex Contact Lens Company
Contact lenses are a modern way of correcting vision. The market has grown rapidly and changed tin character in recent years. Prices have remained high, but Rex Contact Lens Company came up with a plan for selling contact lenses by mail, a system that would permit it to sell at a much lower price than was currently available. Before making the investment necessary to develop this new channel of distribution, Rex wanted to make a better forecast of possible sales than it had made up to date, and it chose to use the survey method for the forecast.Two thirds of the total retail market was estimated to be replacement sales. The average life of a contact lens was thought to be about one year. If 20 million wore contacts and replaced each lens once a year the total replacement market was 40 million lenses a year.Rex‘s concept was for a mail-order replacement service for contact lenses. Catalog sales wore booming in many product areas. And the proposed plan would fit with this national development. A catalog would be prepared with pictures and descriptions of contact lenses and their advantages. A toll free number would be provided for quick service. Lenses would be shipped in sealed bottles within 24 hours of receipt of order and overnight delivery would be available at extra charge. Customers would mail in orders with payment or provide credit card identification for phone orders. Customers‘ for a single contact lens were projected much lower than the current market level 0 and in addition, this low cost would reduce or perhaps eliminate customer need for insurance.Before going further, Rex set about to make an improved forecast for sales. They conducted a survey among wearer of both regular glasses and contact lenses to determine their attitudes towards the proposed mail order sales; the services they would want, the different kinds of contacts they were interested in (hard, soft, extended wear, gas permeable, tinted, bifocals); and the probability they would order lenses by mail.
