It is not currently possible to directly send products overseas from the photo lab. However, we do have a solution.
If you would like to send your products abroad, you can do this through reshipment. What this means is that the lab will send the photos that need to be sent abroad to you and then you can resend the products. You also have the option to charge your customers extra to send the products abroad.
You can set this feature up in Settings > Sale Settings > Shipping settings.
