With a large selection of Hybrids and other strains you really cant go wrong. Some things i can point out are the occasional promotions discounts and even free samples that one might get on special notice.
It's a great delivery service, give them a try affordable prices and overthetop quality.
PS: Give the "dragon" a try ... in short terms its damn fiery!
SF Green Delivery Rocks! They have a very easy sign up process and offer a great selection of medicines. My favs are the Blackberry Kush and Grand Daddy Purple but and deliveries throughout San Francisco are free, fast and friendly. Thanks for this awesome service!
