As people find increasing opportunities to be frugal, I hear more and more stories about people who advocate price shopping when it comes time to buy anything. What do I mean by price shopping? I mean shopping at the place that offers the product you want at the lowest price. In some cases, where you are making a one-time purchase such as an electronic device, this can make sense. But, in the case of buying groceries, going to multiple grocery stores to take advantage of sales on different items is a complete waste of time and resources.
