I took a metal shaping class their last March and they offered 25% off to all students for a week or so after the class. Other than that I've never seen them offer any discounts so I'm interested in this thread as well.
I own the previous design 72" box with the 6 roller wheels and am very happy with it. I use the top as a bench after adding the stainless steel top they offered at the time. Wish mine had the power strip however.
