I've used local delivery services for all my needs over the last year & a half. Of the 10 biz I've tried, only District Releaf has been timely, exceedingly communicative, friendly, reliable, generous, etc. 100% of the time. I haven't had to rely on anyone else in the last 8 months. They're an absolute pleasure to deal with.
Of the handful of delivery services I've used in the city, Herban Legends DC is far & away the quickest, friendliest folks. Super easy to work with- their prices are better than most, and they were able to fulfill my order without having to make substitutions. They'll be my first option going forward.
