Walmart offers the Crock-Pot 20-oz. Lunch Crock Warmer in Red, model no. SCCPLC200, for $19.94. (Amazon charges the same for Prime members.) Opt for in-store pickup to dodge the $4.97 shipping fee. That's tied with our January mention and the lowest price we could find in any color by $3. It features a carrying handle and detachable warming base.
