Wal-Mart is taking a pre-emptive strike against protected sluggish holiday sales by lowering the price on toys very early in the game. As the world's largest retailer and the largest seller of toys in the United States, Wal-Mart is really putting the heat on fellow retailers such as Target with this move. There's no one toy that's a runaway hit this season, so price is really going to become the key seller. One recent favorite, the Nintendo Wii, is back on the market after a serious shortage. Clark thinks the Wii is really interesting since it gets users up and out of their seats when they want to play a game. Now is the time to grab a Wii, which goes for the suggested retail price of around $249; don't wait until it becomes scarce again. For adults, the holiday sales season will be very promotional. The prices of hi-def TVs are set to drop precipitously. Clark recently saw Fry's selling a 32-inch hi-def TV for $397 -- so much less than a year ago. Plasma TVs will also be extra cheap, but DLPs remain the best deal if you have the space for them. One word of advice: don't buy a hi-def DVD this season. Wait until the format wars between HD DVD and Blu-ray get sorted out and then buy the winner.
