Well, we do ship quite a few packages, and we use UPS.
I have talked to Fedex on several occasions and have not been able to make anything work. I once asked them for a sales rep to come by and visit with me, and I bet I spoke to 20 people on the phone who all wanted to sign me up, but not one of them could get a commercial sales rep to come visit me. I did finally get one, about 6 months later, and they could not come close to the service I was already receiving from UPS.
The main differences between the Post office, and the private carriers (UPS and Fedex) is the tracking and the size of the packages they will ship.
The Post office doesn't carry any heavy packages so your cue is less likely to have a big heavy box fall on it during sorting. But, unless you upgrade to the more expensive services, you don't get tracking, just delivery confirmation. Also, UPS comes to my door every day. The Post office says they can do that, but not with any consistency that I can count on.
UPS and Fedex both carry large boxes, and I have had boxes smashed and bent over double with each of them. Well, I have had it happen with USPS too. The biggest difference is that with UPS, I can talk to someone with a brain when I have a claim. With the Post office you have no hope! I have several claims with USPS that never got paid. I have never not been paid by UPS. Never!
Shipping out of the county is a whole new issue. The US and Canada have a little agreement called NAFTA, which means for the Post office there basically is no border. Both UPS and Fedex have to act as a broker to go to Canada. I have heard of $5.00 items costing $50.00 in brokerage fees! So, to Canada, I use USPS.
Over Seas, UPS and Fedex are very expensive, and unless it is an expensive package, over $3000.00, I usually use USPS. But, their insurance stops far short of many packages and we have to go to UPS. There are aftermarket "Third Party" shipping companies that use USPS and offer more insurance and better claims service. We are looking at them now.
Well, I am sure that is more than what you were looking for, but I thought I would throw it in anyway.
