Avoid Bottled Water
If you've been avoiding tap water in favor of bottled water, it's time to rethink that policy. For starters, you'll save a lot of money. Tap water costs about one cent a gallon -- and if you pay a dollar for a 16-ounce bottle of water, that comes out to $8 a gallon. That's an 800 percent markup.
And there's really no truth to the commonly held notion that tap water is unsafe: It's regulated by the Environmental Protection Agency -- unlike bottled water, which is actually more likely to come from a municipal source than a sparkling mountain spring. Plus, you'll be keeping all of those bottles out of the landfill!
