Order Changes & Cancellations

Cancelling or Changing an Order

• You may cancel your order or change the delivery address within 24 hours of placing it.
• Because most orders enter processing within 12 hours, we recommend contacting us as soon as possible. Once the status changes to “Processing”, the order can no longer be cancelled or altered.
• To request a change or cancellation, email shop@youyeetoo.com with your order number and details.

Refunds for Cancellations

• Cancelled before shipment: Full refund processed within 3 business days to your original payment method.
• Already shipped / rejected at delivery: The order cannot be cancelled. If you reject the parcel, we will refund the order total minus the original shipping fee after the returned package is received back at our warehouse.

Payment

Please visit our Payment Method page for available options.
If your order status shows “Pending / Waiting for T/T”, your payment has not yet cleared. Sending us a payment receipt can speed up the process.

Shipping Address

• Enter your shipping address in English, without special symbols. This helps the courier system recognise your address correctly.
• We ship to the exact address you provide. If you need to change it, notify us before the order enters “Processing” status.
• Tip: Save your frequently used address in your account for faster checkout.

Receiving Your Package

Inspect Before You Sign

Please check the contents of your parcel before signing the delivery receipt. If you sign without inspection, we cannot be held responsible for damage that occurred during transit.

“Delivered” but Not Received

Occasionally courier tracking (especially EMS) shows “delivered” a little early. Your package usually arrives within 1–3 days. In the meantime, we suggest:

• Checking with neighbours or your building reception.
• Contacting your local post office with the tracking number.

Missing or Lost Package

If a package is truly lost, email us at shop@youyeetoo.com with your order number and tracking number. We will file a claim with the carrier and work with you on a resolution.
