The Money Saving Challenge was about bringing your own beverage when you leave the house:

While you have probably heard a million times it's less expensive to bring your lunch to work rather than purchasing it, you may not have considered the effect of purchasing drinks while away from home. If you spend $1 a day, 5 days a week, you're spending over $250 a year for your drinks. This price can easily be reduced by 75% by simply purchasing the drink yourself and bringing it from home. Best of all, it takes little effort to do so.
