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. (Amazon charges the same price with free shipping for Prime members.) That's tied with our expired mention from four days ago and $6 under the lowest price we could find for a similar item sold elsewhere. It eliminates sticking, binding, and squeaking on various surfaces, and can also be used as a protectant.
Celebrate your big day with free meals -- or desserts -- at more than two dozen restaurants.
