I worked at a lfs, and we sell it for different prices depending on where it is from, usually around 7-8$/lb, ur in florida so you are very lucky, LR is cheap, the reason why we sold that rock for 10$/ lb was because it was a fantastic 30 lbs piece filled with holes and crevices, it was soo sweet, and for size wayne, they got some very large pieces like that and had to ship them in special boxes, it was about 30" long 5-7 wide and like 3-4 thick.
