I am about to put some substantial purchases (private school fees) on the credit card. Mainly to get the points and to take advantage of the 60 day interest free period. Does anyone know how the 60 days is worked out. Is it just 60 days from the time of payment? Or does the billing cycle come into it. I receive my account on the last day or each month when interest is charged (rarely pay interst as always just pay off balance). My aim is to put the PS fees on the credit card and then pay the balance in full at the 60 day point. I notice that the banks are not exactly transparent on this matter.
