I made the mistake of waiting until I got home to discover that my 3.5 gram purchases actually measured about 1.5 grams. Total rip-off but I should have double checked first. Buyer beware.
I had an issue ($20 overcharge...see my other review posted a week before this one).
They reached out, offered to fix the issue and they did. Not easy to find such good customer service elsewhere.
If I'm in D.C. I'm coming here to get my medicine. Highly recommended.
