Calling all middle school students! Take the Googolplex Teenage Shopping Challenge: How would you spend $150 on clothes for school?

Stalked by Googolplex's photographers like stars with their very own paparazzi, Candace, Haley, Justin and Erik meet the charge in Madison, Wisc, and set out on a marathon mall crawl!

The rules:

• Stick to the $150 limit (not even if you kick in your own cash);
• Don't buy anything that won't meet your school's dress code;
• Choose one preferred destination;
• Shop in pairs;
• Compromise with your shopping buddy on other stores to visit;
• Don't split up!

For three of our four teenagers, the first day of school next fall already presents an extra-big fashion challenge. Haley, Candace and Erik are all starting high school for the first time in August. There's a lot riding on the decisions these shoppers make.

Follow our shoppers as they take the challenge. Click on one of the photos below to start shopping!
