On a different side of the coin, as a consumer I try to never use UPS.
THis is because of the policy instituted by the local UPS office where I live.

They will not leave any package unless signed for by an adult (they no longer
accept the yellow sticky notes that you can sign and leave on the door.) This
means that if you are one of the folks that have to work for a living, you have
to either go to their distribution center to pick up the package - a half hour
away in my case, or reroute the package to somewhere that someone can sign for
it - which will add 4 days to the delivery time, provided that they don't loose
the instructions to reroute (which has happened to me twice.)

Plus, my experience is that a package is much more likely to be damaged by UPS
than with either Fedex or USPS.

So the shipping options that a vendor has tends to be a factor when I select who
to buy from. For me, UPS means extra hassle and more chance of damage - and
generally a higher cost than the USPS.
