DiscoverCard has made some improvements to its online features. You can now schedule payments in advance, make payments as often as every three days, and have your payment post the same day if the transaction is initiated before 5:00 pm Eastern.
The last improvement is a nice touch for procrastinators.
I once tried to use a 0% balance transfer offer from DiscoverCard to an unused credit card operated by MBNA, and the results were not pretty.
