Costco’s low-cost strategy can only be successful if it continues to find ways to reduce costs and be better than its rivals at improving efficiency. Consider these functional-level strategies and recommend one to the management team at Costco. 

a. Utilize information systems to better automate the company’s anti-theft processes. 

b. Offer an unlimited number of customized memberships to its customers, allowing them to set sales volume goals and cashback percentages based on their own spending.

c. Continue R&D into its online systems for Costco.com offering to prevent further loss of the business to online-only retailers.
