$400 a zip is the most I've seen here in MI, but here's the thing... here in metro Detroit there ARE people that pay those prices and have no qualms with it. To each their own. So if you do undercut the so called "market" you're only under cutting yourself. I'm not saying it's right by any means but these prices have stayed the same for 10+ years. When and if I have a decent harvest you can bet your ass I will attempt to get top dollar. I didn't create the market here and I definitely won't be the last to exploit it either. Go ahead and hate on me for that if you must. I have one patient and they receive FREE meds, so any donations for the overages is what will help me keep growing for my patient.
