Wal-Mart Stores previewed some of the discounts it plans to offer right after Thanksgiving next week. Black Friday holiday weekend can account for roughly 10 percent of total holiday sales.

Some of the Wal-Mart deals appeared Friday on the shopping site http://www.black-friday.net.

They include a limited number of Nintendo's popular Wii video console for $249.24 on Friday and Saturday. The gaming system currently sells for an average price of $290. A Samsung BD-P1500 Blu-ray Player is listed for $198.00, while another one by Magnavox will be sold for just $128.00. Blu-ray movies are liste for $15-10. A Seagate FreeAgent 500GB External USB Hard Drive will retail at Wal-Mart for $69.00.

U.S. Sales this holiday season are expected to be the worst in years, as the worsening economic climate forces many shoppers to cut out all but the most necessary of purchases.

Wal-Mart's focus on low prices has been a winning strategy in recent months, helping it to increase sal

es and win market share. The retailer also plans to have special sales on its website on Thanksgiving Day.
