5 year old explanation lol: If you want the shiny race car toy it costs $10 and costs $5 for it to be shiny. I’ll pay $10 for you and the store already made it shiny so you don’t have to pay $5 until you get it dirty or have played with it for a while. Don’t keep it shiny, you won’t want to play with it anymore. So we’ll give it away and the thrift store will make it shiny again. The next kid loves it though so they clean it every day even if it costs them $10! We take care of the things we love
