Got word that dim wt has reverted back to only happen if over 5184 cubic inches. Must have gotten too many ccomplaints.
You can simply go to UPS.com right now and type in some numbers and see that the Dim Weight is still in effect. That said like any contract, these are negotiable, I'm certain some customers have had their Dim Weights reduced or waived in full. Perhaps some of the rumor is from a customer getting their dims waived.
