I have no problems with USPS. However, I do have problems with UPS. I once ordered a $150 air filter and it was never delivered to my house. I know it was never delivered because I was at home on the sofa with a clear view of my front porch and the street when they tried to say it was delivered. I wasn't upset over the mistake but was not happy with how they dealt with it. They tried to accuse me of 'stealing' my own package. I have since moved from that house but while I was living there if I had anything delivered I had to be home to sign for everything. Quite the inconvenience. I tried the boycott too but it is nearly impossible because when it comes down to it, I care more about me and getting what I want more than I care about who is getting my business.
