USPS doing their part to eliminate old Mopar parts

Although I Understand a lot of people have had problems with USPS, I have always had 100% good luck with them. UPS is my LEAST favorite. I wish I had a dollar for every time I went to the UPS website and entered exact box dimensions and weight and zip codes; and then went to the UPS store down the street and the actual cost was al least 25% higher. The clerk always says, "Oh well, that happens all the time." It really pisses me off. FEDEX actual cost is always the same as the website.
Because the UPS store isn't owned by, or run by, UPS. The stores can charge whatever they want to.
