That’s not going to stop us though, so get ready to start saving some serious cash. With more and more subscribers cutting the cord and cancelling their pay TV service each month, the last thing your cable company wants is for us to tell you about an easy way to slash your monthly bill. You also might not realize that you can completely eliminate that monthly fee by using your own cable modem instead.Many people are completely unaware that they have to pay either $8 or $10 each month to use their cable company’s modem.Your cable company might not like us very much for telling you this, but it’s so easy to save up to $120 per year on your cable bill.
