Apart from maxing out 401k and Roth IRA, what are other means of saving money?
I think you mean places to put money as opposed to means to save it (?). If you have maxed out the tax-advantaged accounts, then you can look to taxable investment accounts, investing in real estate, loaning it through social lending sites, any number of things.
Perhaps you can be a bit more specific with your particular circumstances and goals?
