Dammit Walt, I can’t NOT like your post. I was JUST wondering the SDT (Same Damn Thing), literally, just TWO minutes ago, after dinner, scrolling about the interwebs, seeing what’s what, who’s doing what, etc.
It doesn’t come into effect until the 5th as far as I know (it could be ups that is the 5th, so confusing)- but I also don’t think the USPS guidelines have been finalised as yet
EDIT:
Ah Found it
April 27, 2021
The U.S. Postal Service ban on mailing vaping products will go into effect on April 27, 2021. After this date , customers will no longer be able to receive vaping products by way of USPS delivery.
