I don't know when it because socially acceptable to return used makeup — maybe it is just the class of shopper that Wal-Mart draws. To me, it just screams "low breeding" to buy a personal product, take it home, use it, decide you don't like it and then return it.
I'm not talking clothes or shoes or sheets or pillows - the things people buy and then return because they don't fit or are the wrong color. I'm talking MAKEUP.
Just today I had to give a woman back $9 on a bottle of something because "it wasn't my color." It was her color for her to have used at least 1/4 of the bottle!
And I always ask "Did you use this?" I just want to know if we can sell it again. If your lips touched that lipstick, we CANNOT SELL IT TO ANOTHER HUMAN BEING! I don't care if you did - you'll get the money back. And they all lie like cheap toupees when they go "I never opened it." Then why are the plastic seals gone? Why does the blush and foundation pad have color on it? WHY ARE YOU SUCH A COW?
If you want to test out makeup, GO TO A REAL DEPARTMENT STORE. There, a trained cosmetics professional will help you find "the perfect shade." They will also allow you to test the stuff to your heart's content. Heck, they may even help you look less like the rear end of a donkey. Department stores charge more for a better product and better service.
If you want cheap makeup, come to Wal-Mart. But don't play "Mommy Dress-Up" at home and then return the stuff when your experiment is over. It is just plain tacky.
