Some credit card companies give you points for paying bills. If you are able to use credit cards wisely, this is another option as long as you pay it off the following month by transferring money from your savings account.
Note: If you have a large amount of equity in your house you should be able to talk to your mortgage company about discontinuing the escrow account. Although interest on savings is low at the moment, you may as well get the benefit of it, rather than letting it sit in an escrow account.
Note: If you are paid bi-weekly you should receive two "extra" checks a year. Plan to use these for annual bills, and lower the amount you save each month.
