Those categories of products aren't commingled though, so what you described wouldn't happen. Edit: Well it could, but it would be from the actual seller you bought it from. Products that have expiration dates or best by dates don't get commingled for example. Here's a non exhaustive list of the product categories that aren't allowed to be commingled by sellers: OTC Medication Medical Supplies and Equipment Dietary Supplements Feminine Hygiene Contraceptives Industrial Supplies Professional Medical Devices Baby Food and Formula Baby Topicals Baby Stroller and Carrier Topicals Infant Toys Baby Feeding Kid and Baby Furniture Sports Equipment Baby Activity Gear Baby Diapering Baby Car Seats Toy Models and Kits Toy Building Blocks Learning Toys Outdoor and Sports Toys Laptop Batteries Phone Batteries & Chargers Fidget Spinners Solar eclipse glasses Normally, the categories are anything that could cause harm if it wasn't what was advertised and categories that they keep identifying as having a large volume of fakes.
