Living a frugal life doesn’t mean spending no money at all. And sometimes, you need to spend a little to save a lot. Here are three examples. First, LED light bulbs. These cost a little more up front, but they use much less energy. This means a savings on your monthly electric bill and a longer lasting light, not to mention a little help for the environment. Next, rechargeable batteries. Again, these cost a little more on the front end, but you’ll save tons, especially when you use battery-draining items like a digital camera. Lastly, invest in a nice water filter. This will save you from buying bottled water, which is definitely a waste of money. It’s definitely okay to spend a little when it will save you a lot!
