During the night, our water heater blew out ~ we looked everywhere for the receipt & warrantee from our Sears purchase of 3-4 years ago, couldn't find it. Called the 800 # on the water heater, Sears had the info on our purchase & the date we purchased it. Within 20 mins we had a confirmation # and were told to pick up a new one @ Sears. The replacement value was between $450-$650 at Home Depot, so we are very happy campers ! Thank you Sears!
