Case - Strategic shift

Walmart's has undergone a strategic shift towards e-commerce and omnichannel retailing, a move aimed at competing with Amazon Prime. While the company has experienced moderate growth in same-store sales, a much more significant increase has been seen in its e-commerce sales, driven primarily by its extensive physical store network.

Walmart leveraged this advantage to enhance both its online and in-store shopping experiences and developed a third-party online marketplace. This marketplace, coupled with the buy online, pick up in-store model, emerged as a key growth area.
