Check out Reefrocks.net You can get 40# of aragonite for 25 bucks and that includes shipping. My shipment was really nice sand. I will tell you that it took almost a month for it to get here from when I ordered it, but for that price the wait was worth it. I talked with the owner several times and he was very apologetic that it was taking so long. He had some issues with his sand guy. I will definitely order from them again even if it does take awhile to ship. I just ran my tank barebottom for a bit.
I'm not really sure if the sand is considered live or dry. It is just advertised as cleaned and washed. It was a little damp when I got it, no water in it, just damp. It's a lot prettier looking than the dry sand I seen at Petco.
