I've been watching this, it's Try-Ply Clad, made by Tramontina (which walmart sells a very similar set) which Cook's Illustrated and Serious Eats rated on par with All-Clad quality. I own pieces of All-Clad, picked up this set tonight, it's on par.
This was ~$250 about 6 months ago. Was $179 about 3 months ago. Now its Marked down to 129.88 making it an incredible deal.
It doesn't supply in Sam's Club website, but it has:
2qt Sauce Pan w/ Lid
3qt Sauce Pan w/ Lid
Steamer Insert for 3qt Sauce Pan
5qt Deep Saute Pan (can double as a 12" Skillet for most applications)
8qt Covered Stock Pan
