Canadian Tire credit card lower interest rate? | Credit card reward programs | Discussion forum

I have a credit card from Canadian Tire for years and the card has 17% interest . Of course I pay it off as soon as I get it and we get about $300 a year in Canadian tire money.I just wonder what i have to do to get a lower interest offer? Do they exist?.
With Capital one all we had to do was pay off cards and not use it for 6 months and they sent us the offer in the mail.
