There is no big deal. I just like to pay when I want to pay. Might be the day the bill cuts or as late as on the actual due date. I just like to control it is all.
I understand those not wanting to use Autopay. I personally haven't had a problem, my parents had a Nightmare with both AOL and Pegasus(when they had Direct) Parents, even closed a card once and AOL still billed it and they were billed on a closed credit card, while fighting tooth and nail to close out thier account.
I only use Autopay for, Mortgage and Car payment, and I recieved discounts on both for using Autopay, both have ending dates, only exception is Vonage, and Vonage emails me the day they process my payment. I don't like autopay on a revolving service items, that get paid one month on this date, and a different date the next month. Or if I close that account, I don't have to worry about them, missing the flag that my account is CLOSED. A problem I have had with companies like Earthlink and local Newspaper companies.
I pay every bill I have online, I still have .34 stamps, use paperless billing on all accounts, as its easier to save away, and I always get emailed the bill weeks before the due date, and plenty of time to fix a problem before it needs to be paid. I prefer to have control over when my bills get paid, prefer to keep my checkbook, balanced as I run it, instead of having to wait for somebody to post something.
