Why buy at Sears or the big box stores like Home Depot or Lowes? This is the same identical product for far less money. I buy them by the case so I always have them on hand as I mow acreage and in a dirty environment. It takes less than an ounce of dirt to destroy an engine. Protect your investment. Great buy and great protection. This is an actual Briggs and Stratton product not an after market product.
