Reliability varies with branch.  I&#x27;ve been generally quite content with the USPS, but my current home has:<p>* mail regularly misdelivered (1-2 piece of mail&#x2F;month, including small packages that fit in the mailbox).  Who knows what mail I&#x27;ve missed that went to someone else&#x27;s house.
* They won&#x27;t deliver larger packages to my house (busy street), BUT the office remains ignorant of this despite regular visits and I usually have to get bumped up to a manager before they &quot;find&quot; my package after insisting it is on the truck.
* ...But they do deliver packages on Sunday (When Amazon is paying them to) 
* Package slips aren&#x27;t always given.  Followup slips DEFINITELY don&#x27;t happen.<p>After being happy with the USPS most of my life, I now have all my amazon packages delivered to a locker because it&#x27;s easier to always have a small amount of inconvenience than have general convenience (UPS and FedEx to the house direct) mixed with extreme inconvenience (USPS making me wait longer to get the package, at hours that don&#x27;t work well with a 9-5 work schedule)
