USPS v UPS

So I ordered a product last week and the company I ordered it from uses UPS which then uses the USPS system. So UPS gets the package to a set destination and then USPS gets the package to your doorstep. Makes sense right? I thought so until I ordered the product. It took UPS less than three days to get my product from California to Ohio it then took USPS almost a week to get the box from Ohio to Lansing. Making it late I might add. Anyone see the irony in this?

Just one more reason I believe our postal system is fucked and is still being run as a government agency rather than a business like it should. When will we learn?
