Re: Paypal service
Yes, we use it and have never had a problem. It seems to be very safe.
I would say that you have to watch for bogus/spam emails purporting to be from Paypal...but then we get emails from Banks who we have no account with and spam emails from supposedly our own Bank too!
I delete them all and never open any of them - they can write or 'phone me if it's so important!
