Why would a business selling fur coats want to limit the discount on them during a promotion?

a. If prices are too low, customers will question the quality.
b. A discount suggests that the product is defective and unsellable.
c. No one who buys luxury goods will participate in a promotion.
d. Few customers will buy more than one, so a discount is irrelevant

a. If prices are too low, customers will question the quality.

Discounting fur coats too much may give the impression that they are not high-quality products, potentially damaging the brand's reputation and turning off potential customers who are willing to pay a premium for luxury items. By limiting the discount, the business can maintain the perception of exclusivity and quality associated with their products.
