Retailers Team Up Against Amazon

Under a cooperative program called ShopRunner, launched on Tuesday, the retailers are mimicking Amazon by dangling a $79 loyalty program that offers unlimited two-day shipping. But in this case it's across all of the participants' online stores, whether it's Babies 'R' Us, Pet Smart, Dick's Sporting Goods, GNC or a host of others. One-upping Amazon, ShopRunner will offer free returns.
