This is by far the best price I have seen on a triply cookware set after looking around for a few months. This comes with many more pieces than the popular tramontina set sold at Walmart that compares favorably to the highly rated All Clad cookware.
Edit: The lowest price of the amazon version of this set was $209 over the last year or so. So this is $60 less and includes an extra 12 inch skillet (retails for $60 on Amazon).
EDIT #2: I have attached photos of the box and one of the pans for your benefit.
