Discuss the advantages and disadvantages of rebates for the customer and the manufacturer. Are mail-in rebates (for example, at Best Buy) a method to divide customers into categories? How does a mail-in rebate work? How does a supply chain benefit from it? Why does a customer have to "mail in" to get the rebate? Do you think it is unethical on the part of the manufacturer (for example, HP) to offer a mail-in rebate? Discuss with reasoning. Please have this done by a US English writer
