I found mine online, but it was 4 hrs away, so I ended up hopping in the car and going to get it myself, that way I could pick out the pieces. The guy could not believe I would drive 4 hrs to get rock, so he discounted me a little more, so I ended up getting 50lbs for 300 cash. Maybe look for someone online, who is set up relatively close to you, you might be able to do the same thing.
