I would go with one of the edibles deals personally. The other coupons are rather common deals. Also the whole top shelf vs mid shelf sales tactic is bullshit for the most part. Usually I just avoid stores that have that type of pricing structure. If they grow worth a shit then it should all be high quality. The best thing to do is make some friends. The best weed in Colorado isn't in the stores, and certainly not the retail places.
Depends on where you go. I've had "dank" from Cali that was pure garbage. You can find great stuff here just like you can in Cali. It is true that some shops sell rushed low quality product, also just like Cali.
