We’ve had trouble with USPS delivery in my neck of the Upstate NY woods for years.
Including issues with Priority Mail, signature required...
I’ve told small businesses that I use that if my only choice for shipping is USPS, and I’m happy to pay for UPS or FedEx, then I’ll use another biz.
When ordering merchandise online I always try to verify who the carrier will be......if it’s USPS I always try to find the item elsewhere that uses practically ANYBODY but usps.
We once mailed a payment to a credit union literally across town and it never reached the destination.
Absolutely unacceptable.
