As said altitude organic medicine has great quality for the price, although sort of hit and miss in my experience as far as quality.
Pink House in Co springs has some of the best meds in the springs, but I personally don't really like their attitudes and don't really like trading with huge companies like that all that much.
Marimeds in Co springs has very good, consistent meds at good prices if you get a 1/2 oz+, otherwise are a bit pricey.
Oh and one of my favorites which has GREAT quality at good prices is Natural Mystic Cannabis Cargivers. They also have the best customer service I have found and truly care about their customers.
One more worth mentioning would be The Healing Canna. They have pretty good product, but I personally don't like their pricing.
