Orders remain subject to matters such as:

Payment authorization

Where an order is cancelled after payment has already been successfully collected, an appropriate refund will be issued through the applicable payment method.

Taxes
Shipping charges
Other applicable checkout adjustments

The complete amount payable will be displayed before the order is submitted.

If a material pricing error affects an order, we may contact the customer before fulfillment.

Where permitted by applicable law, we may cancel an order that resulted from an obvious or material pricing error.

If payment has already been collected and the order is cancelled, the applicable amount will be refunded.

for processing before shipment.

10–20 business days

Delivery times are estimates rather than guaranteed delivery dates.

Actual delivery times may be affected by:

Other circumstances outside our reasonable control

19. Tracking

20. Multiple Shipments

Products from a single order may sometimes be fulfilled or shipped separately.

As a result:

One order may arrive in multiple packages
Packages may arrive on different dates
Different tracking numbers may be issued

The arrival of only part of an order does not necessarily mean that the remaining items are missing.

Customers are responsible for providing complete and accurate delivery information.

Incorrect information may result in:

Delivery delays
Delivery failure
Returned parcels
Additional carrier handling
Other fulfillment problems

If an address error is discovered after an order is submitted, customers should contact us as soon as possible.

Address changes cannot be guaranteed once fulfillment or shipment has begun.

22. Changes to an Order

Customers who need to request an order change should contact us as soon as possible.

Depending on order status, we may be able to assist with changes relating to:

Product option
Quantity
Contact information
Shipping information

However, order changes are not guaranteed.

Once an order has been processed, packed, transferred to a carrier, or shipped, changes may no longer be possible.

23. Order Cancellation

Cancellation requests should be submitted as soon as possible.

Where fulfillment has not begun, we may be able to cancel an order.

Cancellation may no longer be possible once an order has been:

Processed
Packed
Prepared for dispatch
Transferred to a carrier
Shipped

If cancellation is no longer possible, an eligible return may need to be requested after delivery.

30 days after delivery

Return eligibility is subject to the conditions stated in our Return & Refund Policy and applicable law.

Customers must contact customer service before sending a return.

Do not automatically send returns to our registered business address.

The appropriate return location may depend on:

In suitable protective packaging

Specific return conditions may vary depending on the circumstances and applicable law.

For example, different arrangements may apply where:

The applicable return shipping arrangement will be determined in accordance with our Return & Refund Policy and applicable law.

27. Refunds

7 business days

after the applicable review or approval process has been completed.

After a refund is issued by zoustack, additional processing time may be required by:

Banks
Card issuers
PayPal
Digital wallet providers
Other payment processors

The time required for funds to appear in a customer's account may therefore be longer than our internal refund processing time.

Visa
Mastercard
PayPal
Apple Pay
Google Pay

Where applicable law or transaction circumstances require another arrangement, an alternative method may be used.
