How to know it worked
- An active subscription is what keeps the 20% membership discount. Cancelling removes that discount unless you start a subscription again.
- Each subscription order is charged the same amount unless you change the subscription.
- A phone or email cancel can take up to 72 hours.
Watch out for
- The 20% membership discount requires an active subscription. Cancelling removes it until you subscribe again.
- Pausing is not cancelling. A pause lasts until the resume date you pick. If you do not pick a date, the terms say it stays paused.
- The terms do not publish a dollar price for a pouch or a box. The charge repeats at the amount of that subscription until you change it or cancel.
- The contact block is dated May 1, 2023. It lists Four Sigma Foods, Inc., 1450 2nd St, Suite 210, Santa Monica, CA 90401.
Four Sigmatic refunds
- If you are not satisfied with a purchase from foursigmatic.com, or from an authorized US seller, email support@foursigmatic.com. They say they have a money-back guarantee and will refund the product.
- That guarantee does not cover products from unauthorized sellers.
- The terms do not say cancelling, by itself, refunds an order already generated.
