CTFO Autoship Pricing Information
Autoship Pricing – If you are a Preferred Customer or an Associate and you decide to setup an Autoship (an Autoship is an automatic, monthly recurring order), then you will unlock Autoship Pricing, which is approximately an additional 5% off of the Wholesale Price. Even better news, this is not just limited to just your Autoship orders! As long as you have a valid Autoship on your account, even one-time orders that are placed will use Autoship Pricing.
Some packages and items may not be available for Autoship and may not be available for Autoship pricing because they are already discounted as much as possible.
