As for me, I stretch out my term only up to a certain number of days after my purchase. Because my purpose is only to have enough time to schedule and pay more than one purchase at the same time and in one checking. This valuable piece of info is nice and becomes more important if I'm on a trip for example and can't go to the bank or online ASAP. It just buys me time to organize things while earning miles and claiming rewards at the same time, as compared to paying it straight cash (I don't want carrying a lot when I'm out) =) It also delays me buying stuff I don't need (like saying "I'll just buy this after the cut-off because I don't want it as an expense this month" then I forget about it haha).
