I'm not sure it this is really the best forum for this, but I thought folks here might want to know... I just shipped out a bass to another TB member in a trade, much as I have shipped plenty of other stuff. Weighed it, paid for it, dropped it at a UPS store. Going over my bank balance, I found a $30+ "UPS adjustment" added to my charges, out of nowhere. I contacted UPS, and they explained that box was pulled for "a random audit" and determined to be oversize, so it was upcharged based on "dimensional weight." (Never mind that mass and volume are different properties...) I was completely civil, and UPS responded by being very nice, and removing the charge. But I'm still really amazed that they added this to my card without notifying me, and that they did so after accepting the package--and weighing it--at one of their retail locations. Be aware of this when you're shipping out basses, folks. I've shipped a lot of big packages through UPS, and they are my shipper of choice, but I've never heard of such a thing.
