Orders are generally processed within 2-4 business days after successful payment authorization. During holidays, promotions, product launches, or unusually high volume, processing may require up to 5 business days.

Business days exclude Saturdays, Sundays, and applicable public holidays.

Standard U.S. carrier transit is generally estimated at 10-15 business days after dispatch. Total time from order placement to delivery includes both processing and transit time. Estimates are not guaranteed arrival dates.

Available shipping services and applicable charges are displayed at checkout before payment. Charges may vary by destination, product, package size, promotion, or selected service.

Depending on inventory, product type, and destination, orders may ship from facilities or designated fulfillment partners used by Shanghai Jiduiyu Network Technology Co., Ltd.

When tracking information becomes available, it is normally emailed to the address supplied at checkout. Carrier systems may require time to display the first scan.

Contact us immediately if an address is incorrect. We cannot guarantee changes after fulfillment or shipment preparation has started. Customers are responsible for providing a complete and accurate delivery address.

Availability varies by carrier, product, and destination. Some products or shipping services may not be available for P.O. boxes, APO/FPO addresses, or U.S. territories. Available options will appear at checkout where supported.

Tracking events may be delayed or may not update at every transit point. If tracking remains inactive for several business days, email us with your order number so we can review available information.

If a shipment appears lost, contact service@alvencrest.com. We may ask you to confirm the address and cooperate with a carrier investigation before a replacement, refund, or other solution is provided.

Check your mailbox, property, household members, neighbors, reception area, and any carrier notice. Contact the carrier and our support team promptly if the package remains missing.

Contact us within 7 calendar days after delivery. Include your order number and clear photographs of the product, exterior packaging, shipping label, and issue. If an error attributable to us is confirmed, we will provide an appropriate solution without requiring you to bear additional costs caused by that error.

Delivery may be affected by weather, carrier congestion, customs processing, transportation interruptions, address issues, security checks, public holidays, or events outside reasonable control.

Where international delivery is available, delivery periods vary. The recipient may be responsible for import duties, taxes, brokerage fees, or customs charges unless checkout expressly states otherwise.
