Can anyone tell me about Mary Kay virtual makeover?

My mom is going to buy me first make up kit and I am 13 only. I want few brushes, foundations, powder, blush, and some lip products from Mary Kay. I have heard a lot about Mary Kay virtual makeover products also and I want to know what are the products that I can get in it? But before I buy that I want to know are Mary Kay products good? Does u think it is expensive?
