Hi lmrntx,
We will send you an invoice for your subscription fees during the first week of each month (typically on the first business day) and will then charge your automatic payment method for any remaining balance that is due 3 days later. Each invoice you receive will state the specific date on which your automatic payment method is scheduled to be charged.
If the amount owed listed on your invoice has been paid by the scheduled automatic billing date, your automatic payment method will not be charged. Therefore, if you were to make a manual payment for balance due when you get paid on the 3rd of each month, it should not be necessary to charge your automatic payment method.
You could also potentially make larger deposits into your account periodically that are sufficient to cover more than one month of fees. If you were to deposit some funds into your account in excess of any balance owed, your subscription fees for each month would just be automatically deducted from your prepaid balance until it runs out.
Finally, you could consider purchasing a prepaid annual plan (1, 2 or 3 years) so you do not have to worry about making payments to your account nearly as often. If you mouse over the "My Account" tab within your account, select the "Change Plan" option and click the "Choose" button under the desired plan, you will see the prepaid options associated for that plan on the ensuing page.
If you were to purchase a prepaid version of the plan which best meets your needs, you would also save anywhere from 16% to 25% (depending on the number of years) compared to using the monthly version of that plan for the same period of time.
