I don't think I've paid a bill OFFLINE since early 1995.

I have 5 online banking accounts with 5 different banks and they all offer payment and transfer scheduling. I don't have deposit accounts with all 5 of the banks though. The interfaces and abilities vary, but they can all be set at least to a specific date each month with a specific amount for the payment. Generally I can also specify whether the schedule will repeat perpetually or occur a specific number of times instead.
