loyalty program analysis

Overview: Student will choose one of existing loyalty/rewards program. Students will be required to describe overall concept of the program, detailed explanation of the mechanism, and your own evaluation on the success or failure of the program.
Evaluation Criteria: Your project will be evaluated for:
Level of understanding (i.e. objective, target, mechanism, incentives to customer, benefits to company, etc.)
Level of analysis (i.e. identifying issues, suggestions on improvement, etc.)

As professor request, do not use Sephora and Starbucks.
I will suggest Tarte (Cosmetic & skincare retailer)
