Cheapest I got was for free. Well, not free exactly. We paid about $1100 for a grow setup, but we made that back by selling a lb with 3lbs left over for the rest of us, split 3 ways, so I guess, $366 for a lb.

In terms of actually paying, $50 for an ounce. It wasn't dirt weed but it was loaded with seeds. I'm guessing only about 1/3 of that ounce was actual smokable material. I saved most of the good seeds and now I have at least 40 of them downstairs.
