Wow that's deep!
I however mostly prefer paypal payments because I have a paypal bussiness card and it works like a credit card but you don't use credit, you use cash. It's great when I have to special order something online because most places only take a credit card.
I know they don't always give addresses but when I usually give my payment info out, I ALWAYS give them my home address as well and if they want my home phone number then that's fine with me.
So paypal is good but always ask for the commissioners Address, Email address and even phone number if you want. I for one have never had any problems with paypal but you know scam artists and theives find ways to rob you no matter what anyways, That's why we just have to be careful.
