Crock Pot has the 20oz black lunch crock with an additional warming bowl for $13.49.
The emerald color is also on clearance with an extra warming bowl for $14.49.
I know there was just a recent deal on the lunch crocks but these both come with an extra warming bowl and you don't need to buy 3 at a time to get this price. Shipping is expensive unless you reach $50, then it is free.
There is also a Programmable Lift & Serve Hinged Lid 6quart Oval cooker on clearance for $26.49.
The clearance section has several deals depending on what you need/prefer.
