Wal-Mart offers free shipping

Wal-Mart is giving free shipping to customers if they agree to pick up the product at its stores, in a new program called Site to Store. The company may be the world's largest retailer, but has been struggling to balance its mix of low prices while still pursuing an upscale strategy for its online division, where it sells higher quality products including cashmere items. Most products purchased online arrive in stores in 7-10 days, when customers will be informed via email. The company has made this service available at over 750 stores and will be introducing it in over 3,300 stores later in the summer.
