I shipped a $80 keyboard with MyUS. They charged $35 for shipping. Then FedEx which was their carrier asked for additional $30 as a handling fee in addition to customs. I refused to pay that and their representative hung up. Then nobody answered at FedEx and no one at myUs could provide useful information.
After a month my package returned to MyUS center, where they instantly charged me $270 for the FedEx return shipping and want me to pay again for a second shipping to my address.
Never in my life have I been so outrageously wronged by a delivery company. That whole fiasco sent me back $300 and I still haven't received my package.
