My Style of Saving Fragrances and Cosmetics

Girls are fashionable in different ways.We buy various fragrances ,lotions ,soap and cosmetics to put in our body to look good.How can we save buying those stuff? Those are not basic needs but it is our fashion to take care of our body.isn't it?For cosmetics, I seldom buy lipstick of different shades two or three will do.My technique is to mixed light color to dark to shade a new one! I buy a water proof blush on for lasting shadow in my cheeks.In lotion and baths stuff I bought a bigger bottle because it is quiet cheaper compare to smaller one.If I there is a new product that I want a smaller bottle will do for testing the quality if it's good or not.
