They're a fairly kind and trustworthy company but the "shatter" they sell is refrigerated brown sap and it comes in wax paper. I wouldn't go here for concentrates if I were you.
I've tried multiple services listed on this site that deliver to the boston area and BBB is the only company that never cancels, never gives me subpar product, and never leaves me wondering if it's ever going to show up. Unfortunately they don't sell the concentrates that I'm looking for so I turn to other services for that. But when it's flower my money only goes to BBB.
