I don’t think it has settled in yet, quite a few long running forum controversies have just suffered a huge shift.
Controversy: FBA gives more tax liabilities to sellers than common carrier FBM.
Resolution: Not any more
Controversy: Supreme court decisions and practical considerations make enforcement of remote seller sales tax impossible unless congress passes new laws.
Resolution: Conflicts with observable reality
Controversy: States will have to win a court case before any sales tax gets collected by remote sellers. They are afraid to sue and lose, so are just bluffing.
Resolution: Amazon doesn’t think so
Let me repeat again how amazed I am that this didn’t come at our (third party seller) expense.
