SE Medium Thread for beginners

Hi, have you ever had an experience in shop and ship internationally with any package forwarding Company? If you have kindly shared your experience with these companies. I am looking to buy beauty products on Amazon but they are not shipping to my country. So, that's why I am looking to use the addresses of shipping companies. Kindly leave reviews regarding these companies. Globalshopaholics.com, Myus.com, stackry.
Thanks in Advance. :-)
