Yes, I print my own label. If they weight it and change the weight they just move it to the correct amount you should be charged. No different than if you put the correct weight to begin with. At least this has been my experience. I’ve never been “fined” for incorrect weight and I’ve been doing this for 3 years.
I'm like 82% sure that they adjust at sorting facilities because I always look at what my expected charges are before printing the label, and I feel the actual charges always come out higher. Mine usually run $25-30 and weigh somewhere in the 15-20lb range.
