There's always a little wiggle room.
If you're willing to make a phone call, then make a deal. You can save hundreds of dollars a year on your monthly bills.

In tonight's on the money report, Lynda Baquero explains exactly how to do it.

You've seen the ads countless times, for cable, internet and wireless services.Those monthly bills can add up, and it might seem the rates are set in stone.

The ads are usually aimed at new customers, but Angie Hicks, founder of the consumer website, "Angie's List" says you should ask your provider for the same deals, even if you're not a new customer.

Hicks says, "I've heard stories of people saving $20, $30 a month on even just one of the three kinds of personal communication bills, so it can really add up to some significant dollars over the year."

The key is to ask for a particular department.

"If you've been a longtime customer of the provider and you've been a good customer, you pay your bills on time, then the best department for you to ask for is the retention department instead of just the straight customer service department," she says.

Look at how many cell phone minutes you actually use, and which cable channels you really watch.

Hicks adds, "ask about introductory rates, ask about how it needs to be handled at renewal time. Is it only good for six months? What will my rate look like after that? And also, what kind of cancellation fee might there be if O decide to switch."

Angie says if your rate does go up again don't hesitate to call. She says the worst that can happen is that they say no.
