The Roger's card has 1.75%....I switched to Rogers from MBNA because MBNA changed their cash back rewards formula last year....I think the MBNA (world elite) is actually 1.75% now.....MBNA has an annual fee, which Rogers does not
I also ran the numbers on the 4% cards in select categories (grocery, gas, etc). A vast majority of our purchases are from Costco and Walmart, which do not qualify for 4%. So, 1.75% on everything is better than 4% on some things and 1% on everything else.
Some people use multiple credit cards to capture the best of it all...that's too much effort for me.
