Are you saying that every person who has a credit card in New York state is charged sales tax on all of their purchases——even if such purchases are made while you are on a trip in another state???
It happened to me.
I wasn’t even on a trip. My daughter simply made the charge in the local Dell Store in Nevada and NYS charged me sales tax. I called to complain and they said they had the right. I think they are making it up, but I got the bill, nonetheless.
