Joel covered a lot this week, so here's a quick outline of what you need to know to get yourself on your way to financial happiness:
Inflation is going back up a bit and so are the prices of day to day needs. There's even a pub in London that has implemented new "dynamic pricing" for beer. No one likes prices going up, but it's something that will happen sometimes. The issue with this pub is how they advertised it. They focused on the price increase, instead of advertising sales such as happy hour.
Comparison shopping is a frugal person's best friend, but be careful for some bigger purchases such as insurance. It's important to shop around for insurance every year or two, but if you're using an aggregator site, they may not be doing as much as they promise. They may not have the transparent pricing that you'd want, and there are some insurance companies such as State Farm that do not participate in them. So it's important to use both tools of aggregator sites and talk to actual agents and get quotes that way.
