Welcome to Wal-Mart High!

It's springtime in Texas. The weather is warming up and the air is thick and humid as students count down the days until summer break, but inside one Houston-area high school, a group of students isn't exactly tied to their desks. They aren't in the gym, in home economics class or studying math. These students are inside Scarborough High School's mock Wal-Mart store. The store is a lab of sorts, set up and paid for by the retail giant, complete with a cash register, shelves of inventory and those familiar "rollback" pricing signs on each display.
