Twice this has happened. This weekend i paid 15$ for a pair of earrings. When i got home i realized they had rigged the earrings to look whole, it was taped just enough to hold earrings but once i got home they quickly feel apart .Last time i realized the shoes id bought had a loose heel theyd used gorrila glue to temporarily fix .I know it's a 2nd hand store, but they are very dishonest. Why would i want to buy something that's broken.
