1. The warehouse order volume is too large, which needs 4-5 working days to process (not within the logistics time). 2.Free delivery, choose the most economical distribution logistics, such as natural weather, human factors, logistics system and remote areas, booking time is roughly one to two weeks, more than two weeks to give corresponding compensation. 3. Confirm that your delivery address is correct before purchase, logistics can not change the address, such as lost items buyers bear the cost. Due to the risk of losing items, various PO BOX addresses do not accept purchase requests. 4. The warehouse cannot synchronize product inventory at any time. If we run out of stock, we will notify you immediately and refund you. 5. Return after sale, refund immediately after receiving the product. 6. It is normal for different brands of mobile phones and computers to have slight color errors when displaying pictures. 7. We have multiple warehouses and random deliveries. Thank you for coming. Thank you very much!
