I know, I got mine BEFORE the K-Mart merger/buyout/etc. I noticed on the newer receipts that they no longer done that. Maybe they finally caught their mistake and realized that it was not a smart thing to do.
Sears warranty is VERY VERY expensive. Sometimes the warranty is about half the price of what the item costs. With some things it is a good investment, others it aint. It is NOT a good investment though if they are not going to repair the item.
