Estimated carrier transit for supported United States destinations is generally 10–15 business days after dispatch.
How much does shipping cost?
Available shipping methods and applicable shipping charges are calculated and displayed during checkout before payment is completed.
Where are orders shipped from?
Depending on inventory availability, product location, and destination, orders may be fulfilled from our facilities or designated fulfillment partners. The shipment origin may therefore differ from our registered business address.
Will I receive tracking information?
Once an order has been dispatched and tracking becomes available, shipping or tracking information will normally be provided using the email address supplied during checkout.
What should I do if tracking stops updating?
Contact service@oacmasl.com with your order number. We will review the available shipment information and investigate with the relevant provider where appropriate.
What if tracking says “Delivered” but I cannot find the package?
After reasonable checks of the delivery area, mailbox, household members, building reception, neighbors, or carrier where appropriate, contact us if the parcel still cannot be located. A “Delivered” status does not automatically prevent review of your claim.
What is the return period?
Eligible products may be returned within 30 calendar days after confirmed delivery.
How do I request a return?
Email service@oacmasl.com with your order number, the item you wish to return, the reason for the return, and photographs or videos where relevant.
Where should I send my return?
Please do not automatically send merchandise to our business registration address. After your request is approved, customer support will provide the appropriate return warehouse address and instructions.
Who pays return shipping?
Customers are generally responsible for shipping costs on preference-based returns. If a confirmed problem is caused by an error attributable to us, we will provide an appropriate solution without requiring the customer to bear additional costs caused by that error.
How long does an approved refund take?
After an approved return has been received and inspected, the eligible refund is initiated to the original payment method within 5–10 business days. The payment provider may need additional time to post the credit.
Can I cancel an order?
Contact us as soon as possible. We will make reasonable efforts to cancel an order before fulfillment begins, but cancellation cannot be guaranteed after processing or fulfillment has started. No cancellation fee is charged when an order is successfully canceled before fulfillment.
What if my item is damaged, defective, incomplete, or incorrect?
Contact us promptly with your order number and relevant photographs or videos where appropriate. After review, we will provide an appropriate replacement, refund, reshipment, or return solution for a confirmed error attributable to us.
How can I contact customer support?
Email service@oacmasl.com. We aim to respond to customer inquiries within 1–2 business days.
