Honestly, this place is great if you love wasting your time squinting at glass cases. There is no menu, and the staff doesn't offer a single bit of help or recommendations. Everything is scattered around in cases, so you have to hunt for what you want, try to memorize the exact brand and strain name, and pray you don't forget it all by the time you stand in line and make it to the counter. A dispensary experience shouldn't feel like a memory match game. I left with something, but I won't be back. I'll be taking my business to other spots in the area that actually use menus, show you what's on sale, and have budtenders who do their jobs.

Really enjoyed the vending machines they have to distribute some of the product they have and then of course the incredible amount of product they have. That is the prosser location, but the cle elum location is very personal and they actually get to know u on name basis. And I like that. Plus they are all very knowledgeable of the product they are selling. Thats great. Either way 💯% happy trees 420 is the best pot shop in Washington state. Period. Glad I am a regular customer. Thanks guys u rock and keep up the amazing product and work. Amaze balls. Killer caterpillar. Kool beans burrito. The shitz. Killin it. Thanx y'all.

I won't go back. Last time i was there i got lectured on how i like crappy weed. Their job is so easy, all they have to do is fetch the product that i pick [and like], ring it up, take my money and smile. Can they do that? Just go to Altitudes, they are professional there... Altitudes is really close to this location, and they take debit cards!

Just bought a eigth "Khalifa Kush Violet Sky" and I weighed the contents of the packaging which was some very dark almost purple flower and it weighed out to only be 2.1 grams instead of the labeled 3.5 grams its supposed to be. I would recommend to stay away from this Brand and farm or possibly the store I dont know who's in charge of that or what but its not right.
