How do I know if a website is safe to buy from?
Look at the URL of the website. If it begins with “https” instead of “http,” it means the site is secured using an TLS/SSL certificate (the s in https stands for secure). TLS certificates secure all of your data as it is passed from your browser to the website's server.
Is it safe to buy from a not secure website?
A "Login not secure" or "Payment not secure" message may appear. Dangerous: Avoid this site. If you get a full-page red warning screen, the site has been flagged as unsafe by Safe Browsing. Using the site will likely put your private information at risk.
