Walmart offers the CRC White Lithium Grease 10-oz. Can, model no. 5037, for $2.67. (Amazon charges the same.) Opt for in-store pickup to dodge a $4.97 shipping fee. That's tied with our mention from last October as the best price we've seen. (It's also a current low by $3 .) It's designed for use on brake and gear shift mechanisms, automatic doors, trailer balls, and other machinery, tools, and equipment.
