Order Processing

Most orders are shipped within 3-7 business days after completed payment. 

Shipping Methods

  • We ship orders to the United States addresses only.
  • Our standard Shipment can be either USPS first class or any other service that the shipping department considers most effective at the time of shipping the order.  
  • If the package(s) is returned to us due to an address error made by the customer or the customer refuses the package, the customer will be responsible for the shipping cost for the return of the package.


All purchases made on DA.AI have a 30-day no-questions-asked return period from the date of delivery. If 30 days have gone by, and the item is still under warranty, please contact our customer care staff regarding the warranty process for your item.

Late or missing refunds

It may take some time for banks or credit card companies to process refunds, so please do wait a few days for the refund to appear. If the refund does not appear as expected, do contact your bank or credit card company to check. If you’ve done all of the above and still have not received your refund, please contact us at daaitechnology@tzuchi.us
