Last month, my promotional rate with my cable company expired. That meant my bill was going to jump. Just what everyone loves to have happen. So I called the cable company to see what they could do.
The answer that I got was that they couldn't do much, but that I would be eligible for another promotional rate in three months. I accepted that and hung up with the rep.
A few days later, I decided to call back and reduce my services. Even if it was only a $10 difference, that $10 would add up over the months.
Surprise, surprise, there was no 3 month waiting period for a new promotional rate. In fact, I was eligible for a better promo than I was on for the past two years, with no change in services. So my bill is lowered, and I get to keep all my services.
Oh, and I have to go through this all again next year. But it's worth it.
