Just use ePacket delivery method.
It’s relatively cheap ($0– $3), it has reliable tracking number, and delivery takes somewhere between 12–25 days.
Also, setting the right expectations helps. You should be honest and provide your customers with expected delivery times, you should also warn them about possible delays and don’t be afraid of telling that items are arriving from China.
For as long as items are trackable and your customers can check their order whereabouts your business will be successful.
