I turned off international shipping recently. For different reasons, but I did
have something similar happen during covid. Parcel took 10 weeks with no update
to Europe.
On a different site I use UPS a lot and they have a habit of marking things "delivered"
and then actually delivering it 2-3 days later. They also sometimes forget to
scan things in transit. So that is fun.
Fedex is notorious for employee theft, crushing parcels, and of course, shipping
surcharges that are insane.
Honestly I don't know how all this is going to function a decade from now.
I've already lost the world market a couple years ago, which used to be 1/3
of my sales.
and I'm already noticing that most of my buyers on other sites are from
the states surrounding mine, which means calculated shipping is getting too expensive
to anyone past Texas in my case. I've been looking more and more into local
selling options in person, which of course, has its own set of drawbacks.
