Just had an amazing experience purchased a cart and did not get a battery for a unique set up manager realized that they did not help get the battery needed to utilize the cart given a free cart with the battery. Awesome Team.

I have visited dispensaries nationwide, and this is the worst. Every time I place an order that is an item on sale, the item is always out of stock when I go to pick up. No help to get something different. No discount for another item because of their slow website. Just nothing. They use fake sales to get you into the store and do nothing about it. I'd rather drive an hour out of my way than to go here again.

First time going there as friends told me about the place. I am a veteran and everything was fine until checkout. Instead of giving me the 25% off as stated on the website for veterans for the month of November they said it was only 15%. Not sure I will go back. I should have talked to a manager at the time but I was in a hurry.
