Shopping Guide: 10 Concert-Proof Bags Under $100Earlier this week, I went to a show with my friend Nicole. I had my regular old purse, and Nicole was carrying her tote bag. As usually happens when you go to concerts, Nicole's bag got jostled and knocked over and her wallet spilled out. When it came time to leave, there was a mad search to find her lost wallet on the floor of the club. Luckily we found it, but I promised Nicole I'd do a shopping guide specially dedicated to her almost-missing-wallet and her stupid tote bag, providing better bag suggestions for the future. Let Nicole's mistake be a lesson -- you need a friggin' bag with a friggin' zipper closure.
