One way to save money is to know where it should go every month through budgeting and staying organized. We have been talking about that during our Debt Free Challenge for 2012. However, if you are looking for trusted on-line resources, one site I would recommend is Mint.
This site is free and is a great resource to help you set up and keep track of your budget and your bills. Just knowing where your money goes every month can help you with watching your budget and working yourself out of debt.
