For talking sake's this has really made all of us think how safe is our money online when buying anything thats there we all know we can trust big named sites or gambling sites ect

i have a question we all know when you buy something with our visa we go to a security page..wich goes similar to this appart from the middle 1

tick security certificate is from a trusted certifiying authority

! The security certificate has expired or is not yet valid


tick The security certificate has a valid name matching the name of the page you are trying to view

Is this ok to buy from sites like that
