Dallas-area source for inexpensive holy rock

I hated having to pay around $2.00 a pound at the LFS for holy rock - with a
105 gallon tank, I would have been broke - I found two places near here that
sell the same stuff - at around 10% of the price - after a good rinsing off
with the garden hose, it's good to go - my fish thank me every day.
