I`m Japanese user.
I cannot make it. I tried to logging in my account so many times on MyUS.com. I searched for e-mail address of customer service of MyUS on the site. However I did not find it. So I sent back the first and confirmation e-mail from MyUS to ask help.
Angel, who responds to me quickly like a speed of light. As she instructed I put the numbers and password to the boxes.
At last I made it! My business surely started on this spot, sending my stuffs into Japan.
Thanks great support to me.
