Because we purchase items on your behalf from third-party suppliers, most orders are non-refundable once the supplier has shipped. However, we will assist you in the following situations:
If you receive a damaged item, or an item that is materially different from what you ordered, please contact us within 7 days of delivery with photos of the item and packaging. We will work with the supplier to arrange a refund, replacement, or compensation.
If a package is confirmed lost by the carrier, we will assist with a claim and, where applicable, a refund or replacement in accordance with the carrier's policy.
Contact us at service@bytybuy.com with your order number, a description of the issue, and supporting photos. We will respond during working hours (Beijing Time 9:00 - 22:30).
