Walmart offers the CRC Heavy Duty Silicone Lubricant 11-oz. Can for $2.28. Opt for in-store pickup to avoid the $5.99 shipping charge. That's tied with yesterday's expired mention and $6 under the best price we could find for a 7.5-oz. can elsewhere. It eliminates sticking, binding, and squeaking on various surfaces, and can also be used as a protectant.
