I have a thought about what's going on
This is the 2nd time I've ordered something from USA - Taiwan & received an email that I need to download the EZWAY App from "SF-express", to allow them to act as agents to accept the package. However, my package is not scheduled to arrive for at least 2 more weeks, and it is under the care of Pitney-Bowes, for customs declaration and THEY pay duties on my behalf. Plus, it still shows it is in USA. I think scammers are grabbing a mailing list and just fishing for $ from unaware folk. Taxes/duties/import fees should be covered on your original purchase, no? **BTW, Pitney Bowes have NO contact information either.
