I've been buying since $3.50 and added at $0.60 and $0.40 during the run ups last year. I also got some as low as $0.07.
This might be one of the great stories. Think how good it will feel to load up on this at $0.17 or $0.13 or $0.09 just before the trial results are announced and they launch us to $1+. It will be glorious...just be patient and have your powder ready.
