There is a benefit to scheduling automated monthly billing deductions from payment systems such as PayPal by services you subscribe to. But, there is a down side that is sure to show up at some point. You will get overcharged or overbilled and it will be extremely hard to make things right.
This has happened to me with just about each and every service I have grantted auto payment permission and priviledges to. Sometimes the erroneous billing is an actual error but more often than not you get billed for a higher level of service and at a rate of payment than you signed up for. If it is recurring charge the trick then becomes getting it fixed before you are buried in lost payments. PayPal has been fairly responsive and understanding but the providers often refuse to respond and sometimes are tardy or negligent to make a refund.
It is for these reasons that I will no longer choose this option for payments and even turning off the spigot may prove challenging.
Sneaky Domain companies have been the worst offenders for me. They threaten that your domain will soon expire unless you apply a registration payment which incidently gets elevated to a recurring. They often are not even the company you registered your domain with so obviously there is some spurious scamming going on.
10/24 Addendum:
No sooner had I posted this and I got another bogus charge (this time for Vistaprint).
It suddenly appeared to me that I am caught in a never ending game of Wack-A-Mole. I clobber one mole then another pops out keeping me for ever busy beyond endurance. It aso reminds me of a case of teenage pimples when you pop one only to see another rise up. Whole bottles of Clearisil and ProActiv won’t help.
Personally I am considering shutting off the auto-pay spigot altogether and returning to the cumbersome process of making manual payments.
ALERT: Be aware whenever you sign up for a trial service that you have not committed to a payment contract that goes in place once the trial is over. Seeing something you don’t remember, never used nor ever requested start to draw money monthly from your account can be chilling. Therein lies a trap!
