Right now, Amazon's Lightning Deal HERE is a Calphalon Commercial Hard Anodized 12-Quart Stockpot with Lid for $39.99, down from $168.99 original list price. (More like around $99.99)
These only last for a few hours or until sold out. Whichever is first. So if you need one, I hope you are able to get it!
UPDATE: These are sold out already. Sorry if you missed it. I'll keep my eyes open for more deals on things like these.
