I use PayPal to send my payroll out every week. I know that PayPal first tries to take money out of your bank account, but then uses a credit card if there are no funds available.

Does that mean I can accumulate miles by leaving the account empty, and paying my credit card at the end of each month?

In advance, I know there are better ways to do payroll then PayPal (ala 3.5% charge). Circumstances dictate that I use this system.

Thanks!
