So, I've had a PayPal account for a while now which I've never used, but now I expect to need to use it real soon. I figured that you people here would be able to help me out better than anyone else. My main questions are, "Do I have to have a balance on my PayPal account in order to send funds, or will PayPal automatically withdraw it from my bank account? And if I want to add money to my PayPal account, how long does that take?" Any other info/tips that you want to throw out there would be appreciated as well, since I have no idea of the process involved when using PayPal.
