All our cards get paid in full every month. I put all our business charges on credit so I get a hefty bill every month. Last month I missed the due date thanks to the bill getting here late (bloody stupid Australia bank only gives 12 days before they call it a late payment) and I got hit with about $250 in interest and late payment fees. That's perfectly good cash gone. But the good thing is that we managed to get a few free flights thanks to the points I racked up, like 2 return tickets in business class from Australia to New Zealand plus 2 one-way tickets from Aus to Hawaii
