Make sure that you pay attention to the small print in any "deal" that you sign up for. There have been many times when some small undisclosed fee is automatically added to a bill. By watching the billing and paying attention to all of the fees charged, I have gotten these removed or corrected. This ends up saving me a little bit a number of times. A lot of these fees are automatically assessed and most people don't even notice them, so they just pay and the company makes money. If you watch your bills and make sure that you are not paying for any of these crazy fees, you can save yourself some cash.
