Yeah, this is my question too! And the answers are very vague here! Let's put it more bluntly:
Skeeter, who are you selling your nettles to?
I could certainly use $480 for 60 lbs. of nettles, to get some of my debts paid off, buy seed, etc.
Are you selling them fresh, drying them? Restaurants, health food stores? Or is it a trade secret?
