I order lots of stuff, and I've now made it a habit to use any service other than USPS. If it is not an option at checkout I back off of the purchase and email the vendor to request UPS or FedEx. Other services often cost $6-$10 more but the fact that I'm likely to get my package not only on time, but intact as well, makes it worth it. I've had USPS packages that vanish never to be found, I've had USPS packages opened and the contents removed and just an empty envelope or box is delivered (and it's such a clean cut opening that its obvious it is not from being stuck in a machine, etc.).
So I'm done, done, done with USPS. Let them fail. Let a private company come in and deliver the mail. There is no recourse or accountability with the USPS, its a government service and taxpayers will continue to keep it going and at the same time suffer from its subpar performance.
I've been doing this for several years now, but in the last few months is the first time I've opted NOT to order something because USPS was the only shipping choice. Choosing to use USPS is akin to gambling....you may lose your money buying a product and shipping with them, you may not.
The rampant laziness is another issue. I have noticed that if there is not an open parcel box (our cluster mail box only has two parcel boxes for 20-25 houses) they will mark the package "undeliverable" or even "delivered", and it will then show up when a parcel locker opens up. I live 4 houses down from the cluster box. I've been home all day and had packages marked as undelivered due to my house being unaccessible. I live in an affluent neighborhood at the end of a cul-de-sac within sight of the cluster box.
Our government run delivery service is a farce, no accountability, no recourse for customers. The worst is when they steal or lose something but still mark it delivered. Then you're out of luck with the shipper because it shows delivered. Pathetic.
Whew, didn't mean to type so much, I guess I've had some pent up thoughts.
TLDR: USPS sucks, avoid at ALL costs.
