Sorry to hear it's a bad year for digging.
I took my aluminum cans to the salvage yard a couple weeks ago which is also the ginseng buyer for the county I live in, they were paying $275 a pound.
My guess is this is low because they, well they just seem like the kind of outfit that would price low. But I really don't know.
Also, I have two plants that are still identifiable, but barely.
