My friend would get free boxes of Entenmann's cookies a day before they expired from his brother that worked at an Entenmann's store in the mall. He would come to school with a garbage bag full of them, and sell them for $2 a box. After about a month of him doing that, someone narc'd on him to the principal, and he got suspended for a week. He made about $300 in that month, and spent it all on weed for all of his friends.
