Has anyone purchased soil amendments from RES (Resource Environmental Services) in Eagan, MN? They sell a Garden blend soil (soil/compost/sand) and a Farmers blend soil (composted manure) (among other products) for $20/cuyd. I'm wondering if anyone has comments on the quality of their product. I'm thinking of getting a truck load to start a new garden and to topdress the lawn. Or, does anyone know of a resonably priced alternative?
