We ship with DAO domestically, and the estimated time for arrival is 2-4 days after the package is sent.
For international orders, you can choose between with or without a tracking number. Having a tracking number is more expensive, and that is why you can choose not to have it. We want to make shipping as cheap as possible, therefore it is up to you. We recommend to choose the tracking number option, because if it get lost, we don't replace lost packages without a tracking number.
