Which credit card has the best rewards? I am planning on starting a home daycare and would like to keep all my purchases seperate from my personal ones. I have a PC Mastercard, CT Mastercard, Air Miles Amex and an HBC card for personal purchases. I probably like the PC card the best, Amex and CT close after. It would be paid in full every month, so I'm not worried about interest and do not want to pay a fee. Thanks for your input :)
