nlike you, an open-minded person would recognize there may be business cost attachments associated with credit cards - who knew!
I own stock in banks and get their yearly reports. I also took Business Administration in school
And you?
That CBA list, along with the provided link to CreditCards Canada, offers insight into some of those cost attachments... while also highlighting there are many low(er) interest credit cards available - with some 30 of those with rates below 13%.
Low rates usually come with fine print. Why would a bank offer a rate at 2/3rd of its other rates? To be nice? No, there'll be heavy penalties for late payments, lower grace periods before interest applies, monthly/yearly fees. Etc.
