I don't know about Sears and all, but one nice thing to look out for is price protection guarantees. I bought my Toshiba TV from the Wiz in NYC, and they have a 90 day price protection guarantee against major retail chains like BB, CC, etc. Well, soon enough, about 2 months down the road, the tv dropped it's price $20. Just walked right in with the receipt and they put money back into my credit card. Nice touch.
