[AB] Why is shaw trying to save me money?

Hi, I live in Edmonton. I currenly have High Speed Internet and Home Phone Basic from shaw. It costs me 89.95 a month. Shaw has been calling me this month trying to get me to switch to High Speed 10, Personal TV, and Home Phone Basic for 70 a month for three months - then I can cancel the Personal TV and and my bill will end up being $10 less at 79.95 a month. They did say an installer would have to come out and split the three services into three different cables? That's sounds really good - which is why I'm suspicious - why would shaw be calling me, trying to save me money? Has anyone else gone through this or have any idea of why they want to do this? Thanks
