Bianca Souza
Bianca worked in retail buying for five years before switching to writing, which left her with a near-compulsive habit of calculating cost per use before she buys anything. She runs Glass Skin Diary's subscription and box tests, tracking what she actually paid against what the same products would cost full-size. She cancels every subscription the moment a test ends, no matter how good the box was.
