A new potential customer came to Wayback Homes, offering to pay $20 per unit for an order of 100 old-fashioned toasters to promote a nostalgic feeling in its RVs. The customer is not willing to pay full price for the toasters, however, recognizing that it could go elsewhere and find a reasonable substitute product that would provide a similar customer experience. Accounting staff at Wayback told the sales and operations managers that the special order can't be accepted unless Wayback can reduce its costs by 20%, even though it has production capacity to take on this special order. Some of Wayback's old-fashioned toaster unit costs are as follows.
