Wal-Mart has begun selling the HP-branded iPod on its online store. The world’s largest retailer is currently offering the 20GB model along with a slew of iPod accessories. Wal-Mart is pricing the HP iPod from Apple below retail at US$290.86–a little less than $10 off. Wal-Mart makes it clear that the HP iPod is an online exclusive (not available in brick and mortar stores) and that the player is not compatible with the Wal-Mart online music store.
