How long does order processing take?

Orders are normally processed within 2–4 business days after payment confirmation. During holidays, promotional periods or unusually high order volume, processing may require up to 5 business days.

How long does standard U.S. delivery take?

Standard shipping to supported United States destinations generally takes 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 physical shipping origin may therefore differ from our business registration address.

Will I receive tracking information?

Once an order has been dispatched, available tracking information will normally be provided by email or through the applicable order-tracking method.

What should I do if my package is delayed or missing?

If tracking has not updated for an extended period, your shipment appears lost, or a delivered package cannot be located after reasonable checks, contact service@radvgsk.com with your order number.

What is the return window?

Eligible products may be returned within 30 calendar days after confirmed delivery.

How do I request a return?

Contact service@radvgsk.com with your order number, the item you wish to return, the reason for the return and photographs or videos where relevant.

Do not automatically send merchandise to our business registration address. The appropriate return warehouse address will be provided after approval.

Who pays return shipping?

For preference-based returns, customers are generally responsible for return shipping costs.

If an item is damaged, defective, incorrect, incomplete or materially different from its description because of a product or fulfillment issue, an appropriate solution will be provided without requiring the customer to bear additional costs resulting from that error.

How long do refunds take?

Approved refunds are issued to the original payment method and are generally processed within 5–10 business days after the returned item has been received and inspected.

Can I cancel my order?

You may contact us promptly to request cancellation before fulfillment begins. Cancellation cannot be guaranteed once fulfillment has started.

No cancellation fee is charged when an order is successfully canceled before fulfillment.

What if I receive a damaged or incorrect product?

Contact us with your order number and photographs or videos where appropriate. After reviewing the issue, we will provide a reasonable replacement, refund or return solution depending on the circumstances.
