Suppose that you have two Credit Cards (denominate them CC), each with a limit of $2000 CDN.
CC1 is preferred (because it offers Cash Back), but has a Current Balance of $600.
Thus, even if I pay the $600, then for this month, my CC1 use would still exceed the suggested 30% ratio (600 + 2000).
CC2 offers no Cash Back, and has no Current Balance.
I must purchase something this week that is $2000. Does it matter which CC I use?
