What do retail outlets hope to achieve from using promotions in conjunction with markdowns?

Bulk purchase of products, which reduces brand switching and, in turn, increased consumption

Increased loyalty of customers based on discounts tailored to suit individual customers

An increase in store traffic that leads to the purchase of non-promotional products at regular prices

Increased savings for customers and increased profits, without actually cutting prices

Selling off less desirable products by including them in a package with more desirable products
