I love 3fifteen! Great selection and a wonderful rewards program! It’s easy to rack up points. The associates working are always knowledgeable, friendly, and professional. I “shopped” around a few dispensaries but this one is my favorite by far!

I’ve been to quite a few dispensaries on both sides of the river ( Stl, Mo and East STL, IL) and 315 is the only dispensary that I have been to 3 times!! Usually I visit a dispensary, may or may not make a purchase. I have made purchases each time I have visited here (3 times in last 2 weeks). With that being said, this is my favorite of all the dispensaries I have visited!! I LOVE the rewards program!!!

Great experience every time 👌 Staff is very on point for your needs and that's not gassing them up, they really give a genuine experience every time I've been. The products have all met standards, reasonable prices, they have a great rewards program, staff is friendly willing to answer any questions or get you in and out if that's what you prefer. Also very attentive to pre orders and medical patient needs.

I have been coming here since pretty much the day they opened. First place I used my MO medical card. Since then they have only gotten better as a dispensary. They are friendly and knowledgeable should you want some advice. They have the best rewards program I have ever seen for cannabis. 5% back on every purchase is nice and if you partake once a week, you will find those point come in clutch more often than not. In short, best dispensary in STL.
