Wal-Mart is making Twinkies available this weekend, even though Hostess says it asked retailers to wait until Monday to start selling the spongy yellow snack cakes. The world's largest retailer announced Friday that the cakes were available at about 1,600 stores and that about 3,000 of its 4,000 U.S. stores should have them by Sunday morning. That's a day before the July 15 return that Hostess has trumpeted in its marketing.
