My biggest requirement is accurate lab results so we know what we're buying. "High thcA" is a fine descriptor but it covers a wide range of potencies.

Once that requirement is settled, my next personal preference is not just competitive pricing, but nuanced as well. I don't like seeing every bud with thcA content priced exactly yh same. I want there to be consideration for labor cost, demand, supply, etc. Good business sense is obvious in pricing. Also, inflated uniform pricing tends to indicate they're just a reseller and not connected to the grow op itself. I could be wrong about that but good lord, some of these images are ripped right from other vendors. Of course I'm gonna think you're a reseller.

Oh also, my last sort of personal preference, I like when they have more than just flower available. I've been gettin into concentrates a bit and really want to buy from some of the great vendors I got flower from. It also demonstrates a sort of commitment to the craft. It takes time to make concentrates right, and there's multiple kinds. Having a good selection of high thcA concentrates I think is going to be what really makes good vendors stand out.
