"Trip to the grocery store [1]" is a fun way to see how prices vary around the country, the differences between similar offerings at various grocery stores, and a rough way of tracking grocery prices. The questions come from a receipt from a recent trip to the store, and this one is from Trader Joe's in San Francisco. I love TJ's because it usually has much cheaper prices than other mainstream stores in the city and it offers good-quality items. How money are you?
