Shopping with Trailhead Tea is safe. You never have to worry about credit card safety when you are shopping at our site. We have chosen technology and partners that create an environment so that each purchase you make is protected and safe. By using the latest encryption technology - secure server software (Digital SSL certificates from Comodo) - we can insure that your personal information is safe. You must provide your credit card info each time you shop, since we do not keep it on file. All your ordering information -- including your name, address, and credit card number -- is encrypted so that it cannot be read as it travels over the Internet.
