other sources of laterite

I got a tip to call the Pet Warehouse for a mail order of laterite.
Unfortunately they too have stopped selling it.  Apparently it was too
expensive to ship due to its weight.  Big bummer.  So,  does anyone have a
source of the stuff that isn't Pet Warehouse.  Maybe just a simple pet
store that might be willing to send it to me if I paid the shipping?, or a
store somewhere in the area of northern Indiana (southern Michigan) or
northern Ohio?

Thanks in advance,
