One possible alternative that brick and mortar vape shops should seriously consider is seeing if it's possible to sign up for UberEATS, Gopuff or Doordash.
In some areas of the country, we deliver alcohol, so the mechanism is already in place.
The problem isn't so much lacking mechanisms rather the major burden the PACT Act puts on the mechanisms, which is one reason FedEx/UPS/DHL bowed out even though they didn't have to (the other reason being anti-vape optics IMHO). The burdens of the PACT Act don't apply to alcohol.
