Yesterday when I noticed UPS lable was the first choice Amazon was offering, I was able to check to see what I set up as my carriers choices (No prioritizing, just who you want to show in your label list). I think there is a link/tab in “Buying label” page to do add or delete carriers (I don’t have any FBM order right now to ship, so can’t check that page to be sure). I do want to be able to see the UPS choices, so yesterday I didn’t try to delete the UPS from my list of carriers.
If UPS label is going to be 1 cents less than USPS label, the UPS label is going to be the first chocie in Buy shipoing from now on. Guess I just need to pay more attention to what Amazon is showing as label choices from now on, and not automatically click the first one.
BTW, I didn’t have AHT and SSA set up.
