Instaflex is a company that offers a joint health supplement called Instaflex Advanced, designed to relieve joint discomfort. They provide a trial offer where you get a sample, and if you like it and don't cancel within 18 days, you'll be automatically subscribed to a monthly shipment program. Each month, they send a fresh supply of the supplement and bill you $69.99 plus $4.99 shipping. You can cancel the subscription easily at any time with no future obligations, which means you won't get more shipments or charges if you cancel.

Instaflex subscription has a notable lock-in feature: you must cancel at least 1 day prior to the next shipment billing date to avoid being charged for the next month, and if you cancel the day of billing, you might still be billed for that day's shipment. There's no early cancellation fee, but membership continues billing until you follow cancellation procedures, which require calling or emailing them. Be aware that while you can cancel anytime, failure to cancel on time means you will be billed for the next 30-day supply, and returns require a 30-day satisfaction guarantee process with return shipping paid by you.
Before cancelling your Instaflex subscription, know that you can cancel at any time hassle-free, and you will not be charged or obligated to receive future shipments. If you cancel within 18 days of your order, further shipments and charges will stop, and you can keep your trial bottle as a gift. After the trial, any additional unopened bottles can be returned for a full refund within 30 days of shipment. Cancelling means loss of access to the autoship convenience and any ongoing promotions tied to the subscription. To cancel, you can contact Instaflex customer service by phone at 1-800-436-0920 or email support@instaflex.com for assistance.
