Silverstem Denver SW is my personal favorite. Most dispensaries carry roughly the same products, so the only differences are
Prices: can maybe find better, but why bother looking because...
Customer service: Incredible, knowledgeable, professional, ethical, individuals who actively strive to make each visit your best.
Loyalty programs: find out about their loyalty and membership programs, they are unbelievable.
It is a 60 mile round trip for me, and well worth it.
