Best credit Cards
For the context,, i need advise on how i should use them more efficiently.
I got 7 credit cards total
PC INSIDER WE MC - i use for grocery and gas.
Triangle WE MC - i use for canadian tire purchase, very rare use.
CIBC GOLD VISA - just got upgraded and got first yr fee waiver.. don't use at all. Only if get the balance transfer offer
Walmart World MC - only for walmart purchase if any.
Scotia bank regular Amex - my first card, not using at all. Just have it for my history.
WealthSimple VIP - anything else, i use it like for food and dining and everyday purchases gives 2%.
RBC WESTJET MC - i was pre-approved, i don't know why i accepted it? probably has a fee but waived for first year.
Am i doing anything wrong? Any suggestion for more efficiency in rewards or cash-back.
If any other credit card to maximise rewards that i can apply for
