A firm currently sells its product with a 2% discount to customers who pay by cash or credit card when they purchase one of the firm's products; otherwise, the full price is due within 30 days. Forty percent of customers take advantage of the discount. The firm plans to drop the discount so the new terms will simply be net 30. In doing so it expects to sell 100 fewer units per month and all customers to pay at day 30. The firm currently sells 1000 units per month at a cost per unit of $45 and a selling price per unit of $80. If the firm's required return is 2%, what is the net present value (NPV) of making this change?
