Thanks very much Chris, yes I realised about the credit cards and debit card rules etc so I've never shopped on a site where there is no padlock AND the
https.
My argument with the other person who doesn't bother checking if the site has
https or the padlock but still reckons they would be protected by their card if anything went wrong. I feel that if they haven't made sure to buy from a secure site then the card provider won't guarantee money back for anything going wrong.
I've always understood that the site isn't safe and payments without the padlock isn't encrypted.
