As long as you cut out the middle men, you'll always get a pretty nice deal. The artist usually makes a few extra bucks, too. Just need to find them on instagram/facebook/twitter and get that email address. Every one of them I've contacted have been happy to deal directly, but you do have to be patient. If you want something and you gotta have it right now...that's what the LHS is for.
Also, Lev's glass is pretty cheap for what you get. Cheap isn't a number...it means that you're getting more than you're paying for, and those pieces are solid. I've had my lattice for over a year and beat the hell out of it. Banged it on the sink. Dropped mason jars on it. Kicked it over. A girl smacked it into a metal table. No cracks. I broke the slide it came with in a week, though. haha The glass dots on it made it way to heavy. Broke the first time I dropped it.
