I've been asked if Paypal Friends and Family is a good way to do business and figured I'd include you both in this conversation.
Paypal Friends and Family is not a secure method to do business on the internet. If you choose to, that's up to you but you will have no recourse if you are taken for whatever payment. I personally would not do business that way - as I would build the price in with the added fees for offering a secure transaction.
