I've had about 10-15 shipments sent or received over the past several months with only one obviously delayed shipment.  However, none of them have been international shipments.  

tonygry, do you work for USPS? if so, can you check on a couple missing packages for me?

That's terrible and I'm sure it was sad to see.

I’ve had two tracked packages go missing at various points in transit.  Both sellers were very accommodating and refunded me.

The USPS International prepaid boxed seem to fine. The last couple of times I bought stuff from the US they took about three weeks to arrive, which used to be only 7 days, but tracking seems to indicate that the problem is a UK customs backlog with US side only adding a couple of days to getting them on a plane. Given the current lack of willing employees in the UK (and why would you go to work for the extra 20% if you can stay at home for the remaining 80% of your wages?), and all the idiots who have apps on their phones that tell them they shouldn't go to work, its only to be expected that these delays are gonna happen internationally.

I was getting 6 week delays on products from China and Japan earlier this year, so an extra 2 weeks from the US is quite acceptable to my mind.
Also, so long as the seller uses USPS prepaid boxes, with books and stuff I've not had anything arrive damaged.
A couple of damaged minis, but that was bad packing, not any damage to the box.

Given the tales of woe on this thread, I can only surmise that USPS staff in the US are far more brutal and less caring that their UK counterparts.
We have a company here in the UK that is that bad however. It's called Hermes.
