I think a one stop hydro shop is what a dispensary is looking for. Have you ever gone into Walmart and bought duck tape, a section of lead pipe and, pipe cleaners? You get a visit from the local sheriff. Or go and try and buy 2 packs of sudafed within 60 days. You get a visit from the sheriff.
Mom and pop keep their customers safe and happy. A no brainer. Only a fool would buy from a big box store.
