Did you ever get frustrated at the contestants on The Price is Right for their inaccurate estimates? Then you'll love getting competitive with yourself in my new feature, "Trip to The Grocery Store." I'll test your knowledge about what items cost at the grocery store according to a receipt from my most recent trip. It will be interesting to see how prices change over time and how cost-aware we really are. In this case, the store was Safeway in San Francisco and the trip was just yesterday. How money are you?
