Tax issues:
1. As each country charges different taxes on parcels, you need to know whether the country of your own address needs to charge taxes before placing an order.
2. If you need to reduce the invoice amount, you can contact customer service or e-mail contact.
3.The package arrives safely in the buyer’s country and the merchant is not responsible if the package is (returned) because the buyer has not paid the tax.
Other issues:
If you need to find other electronic products or have any questions you can contact customer service or email. (We will get back to you as soon as possible)
