On the subject of bank transfers, they are not often used for private transactions in the UK, except perhaps with people you know well. One of the problems is that you need to divulge essential details about your bank account number, sort code etc, which are the very items of information that scammers are after to clean your account out (eg the folk in Nigeria etc). For that reason I've never accepted them on the various sites where I've sold items. Despite their faults, using people like PayPal, Google etc is safer.
