contact ADG Shop, they just received a shipment but not sure if aquasoil came in.
you can also call Ridgewood Aquarium Imports in NJ and see whether they ship. That's where I purchased all my stuff....they are literally on the way to my parents' house where I visit every two weeks. If anything I can pick some up and ship it to you...but you have to call them up and see whether they still have it. It's an official ADA store so prices are pretty much the same as ADG Shop.
