This weekend on Marketplace Money, host Carmen Wong Ulrich addresses some usual – and unusual – questions about how family and finances mix during the holiday season. First, reporter Stacey Vanek Smith shares the myriad ways stores use technology to stalk customers while they shop, in hopes of making them spend more money. Plus, psychiatrist Gail Saltz joins the program to discuss how people rationalize overspending on gifts for loved ones and ways to break that bad financial habit. Also, Greg Graffin of the punk rock band Bad Religion reflects on how his spending habits were shaped by his frugal father. And, a pair of personal finance experts debate the value of the financial literacy movement.
