Wal-Mart has begun selling Apple’s iPod mini in a “limited number of stores,” a representative for the discount chain said Monday. “The mini is one of the few Apple products that the discount chain sells, but that may soon change,” reports CNET News.com. “The companies are rumored to be working out an agreement for Wal-Mart to begin selling the iPod shuffle, a new music device that Apple unveiled last month… In any case, the addition of Wal-Mart to Apple’s list of retail partners would expose many more consumers to the product and likely lift Apple’s sales. Up until now, the world’s largest retailer has largely stayed out of the market for Apple products, which typically forgo affordability in favor of sleek design.”
