Saving Money

I don't really pay that much attention to the economy but lately my parents have been a little more stressed out. I have also been noticing our family trying to be a little more conservative with money. We have been doing the following; buying less not useful stuff, my mom is now limiting my brother to 5 minutes in the shower instead of 45, i'm pretty good about turning lights off when I leave the room. Those are the basic things we do to save money.
