Don't sell anything but 8ths and quarters. Say, you sell an 8th for $25 and a 4th for $50. That's $200 an ounce, multiply that by 4, and you've got $600. That's a mighty profit for $250, Now go back, and buy a HP, and keep working your way up till you can start buying 3 or 4 pounds at a time, then you're really bringing in the money.
