Cancellation policy

Cancellation Policy

Last updated: 20 August 2026

Some products in our store may be offered as a subscription, a pre-order, or on a try-before-you-buy basis. This policy explains how each of these purchase types works, how you will be charged, and how you can change or cancel them at any time.

This policy works together with our Refund & Return Policy. For anything related to returning a product or receiving a refund, that policy applies. If you have questions about either, contact us at support@ttsclinical.com.

Subscriptions

How it works. When you purchase a subscription, you will receive repeat deliveries of the product at the frequency you select at checkout (for example, every 30, 60, or 90 days). Your payment method is stored securely by our payment processor and is charged automatically before each delivery, unless you chose to pay for the full subscription term in advance.

Renewal. Some subscriptions renew automatically at the end of their term. We will state this clearly on the product page before you subscribe, and where required we will send you a reminder before any renewal charge.

How to change or cancel. You can pause, change (frequency, quantity, delivery address), or cancel your subscription at any time, with no cancellation fee:

Use the Manage subscription link in any of your order confirmation or upcoming-shipment emails; or
Email us at support@ttsclinical.com with your order number.

Cancellation deadline. To avoid being charged for the next delivery, cancel at least 3 days before your next scheduled billing date (shown in your subscription portal and in your reminder emails). Cancellations made after a charge has been processed take effect from the following cycle; the order already in progress will ship as normal and is covered by our Refund & Return Policy.

Pre-Orders

How it works. A pre-order lets you reserve a product that is out of stock or not yet released. Depending on the product, at checkout we will either collect no payment, a partial deposit, or full payment, and we will state this clearly before you buy. If any amount remains unpaid, your stored payment method is charged when the order is ready to ship. The product page will show the estimated availability date.

How to cancel. You may cancel a pre-order at any time before it ships, for a full refund of any amount already paid, including deposits. To cancel, email support@ttsclinical.com with your order number.

After shipment. Once a pre-order has shipped, it can no longer be cancelled, but it is covered by our standard Refund & Return Policy (14-day return window from delivery).

Delays. If the availability date of a pre-ordered item changes materially, we will notify you and offer you the choice to keep your order at the new date or cancel for a full refund of amounts paid.

Try Before You Buy

How it works. When you order a try-before-you-buy item, we place an authorization hold on your payment method (you are not charged at checkout) and ship the product to you. You then have the trial period stated on the product page and repeated in your order confirmation to decide whether to keep it. We will not offer an item on this basis without stating that period before you order.

If you keep it. No action is needed. At the end of the trial period, your payment method is charged the full purchase price shown at checkout.

If you return it. Start your return before the trial period ends by emailing support@ttsclinical.com with your order number. Returned items must meet the condition requirements of our Refund & Return Policy. Once we receive the item, we release the authorization hold or refund any amount charged.

Please note. If a return is initiated in time but arrives in a condition that does not meet our return requirements, we may charge the full price or a partial amount, and we will notify you before doing so.

General Terms

Cancelling a purchase under this policy is always free of charge; you only pay for products you keep or that have already shipped.
All charges, holds and refunds are processed in USD to the original payment method. Your bank may take 5–10 business days to post a refund or release a hold.
We reserve the right to cancel any order or subscription due to pricing errors, suspected fraud, or product unavailability; in that case you will be notified and fully refunded.
