That's not bad for the price to be honest. I've never done business with liverockusa.com. You could always go for a sample and then get more if you like it. If it's $1/lb, then it's not going to be "designer" rock. It won' be the pretty rock in otherwords. It's going to be some ugly stuff. If you're ok with that, i say try it out and see what happens. Let me know if you do.
