I gotta say, hit up the little arab or asian markets, they usually dont give a fuck what you buy. pretty much any place without a corporate system, if you are legit with them, will hook you up. They dont give a fuck, and their fs charging system doesnt itemize the items you buy.
I used to buy my tobacco all the time at a little arab market in Oakland when I lived there, they were a bit touchy about the alcohol, but the vietnamese market down the street was good for that.
and in NOLA, you can buy just about anything, porn, lottery tickets, alcohol, tobacco....
The shope owners, and the cashiers, usually dont care at all. Just dont be shady in their shops, and maybe even just ask "can I get this on benefits?".
I dunno, seems a lot easier and a lot cooler than trying to pull some bullshit policy scam at walmart.
