Business is all about supply and demand.
The best possible example is bottled water.
It’s everywhere you buy things, usually, but sometimes demand exceeds the supply, and that’s when you can make a killing. My brother Amos would take a cooler filled with bottled water to the parking lot for football games. He’d charged five bucks a bottle, but every single game he would sell out, and pocket a huge profit. Of course, it only worked during that particular situation, because that’s when the demand was the absolute highest. The same is true for cannabis, and once the local dispensary opened up, it has been harder to sell my homegrown product. I have been a local marijuana vendor for a few years now, and it has provided a very nice supplemental income to my day job. I like to call myself a local marijuana vendor, because I think it sounds a lot classier than “pot dealer” although that is what my family calls me. Oddly enough, although I have lost a few customers, my remaining customers are willing to pay more for their cannabis than in the past. Because the cannabis dispensary charges so much more than I do, people just think that is the going rate, so I have raised my prices to match theirs. So there is less demand for my supply, but on the other hand the retail price of cannabis just went up and no one complained, so that has helped offset things a bit. Still, I need to pick up some new customers, or I’ll need to apply for a job at the cannabis dispensary.
